The excerpt highlights compatibility changes developers may need to account for: seeded `Math.random()` sequences change, sorting remains stable but comparator call patterns can differ, serialization data from v27 cannot be read by older Node.js versions, and some caches may miss more often. Default old-generation memory limits increase on machines with 4-15 GB of RAM, while buffers count toward V8's allocation limit; heap snapshots are roughly twice as large and slow to take, and now include full script source, which can expose secrets. The Alpha phase may introduce breaking V8 changes; ABI breaks trigger a `NODE_MODULE_VERSION` bump, and the V8 version is expected to stabilize at LTS. The excerpt also notes improved fatal-error reporting, removal of inspector live editing, and renamed or removed WebAssembly flags. Performance effects vary by platform, workload, and build. ### Source excerpt Node.js® is a free, open-source, cross-platform JavaScript runtime environment that lets developers create servers, web apps, command line tools and scripts. ## Node.js 24.22.2 (LTS) DevFeed: [Node.js 24.22.2 (LTS)]() Original publisher: [Read original article]() Published: 2026-10-28T18:40:14Z Content type: release Language: en Sources: [Node.js]() Topics: [Node.js]() Tags: [64-bit](), [documentation](), [linux](), [lts](), [macos](), [node-js](), [pgp](), [pkg](), [sha256](), [source-code](), [stream](), [v8](), [windows]() ### AI overview Node.js 24.22.2 (LTS) includes five V8 dependency backports or cherry-picks and a stream fix that preserves async context for parked writes. The release provides installers, binaries, source archives, and documentation for Windows, macOS, Linux, and AIX variants.

DevFeed: [Can Agentic Code Review Catch Vulnerabilities Before They Are Merged?]() Original publisher: [Read original article]() Author: Yihan Yang, Chenyuan Yang, Zijie Zhao, Anh Nguyen Hoang, Ziqi Zhang, Weidong Wang, Zhiheng Lyu, Lingming Zhang Published: 2026-10-27T04:00:00Z Content type: article Language: en Sources: [arXiv: Artificial Intelligence](), [arXiv: Cryptography and Security](), [arXiv: Software Engineering]() Topics: [ai code review](), [code security](), [Code review](), [AI Agent](), [known exploitable vulnerabilities]() Tags: [agentic](), [agentic-code-review](), [agentic-security](), [agents](), [anthropic](), [benchmark](), [benchmarks](), [code-review](), [cs-ai](), [cs-cr](), [cs-pl](), [cs-se](), [evaluation](), [firefox](), [frontier-models](), [gpt-6-sol](), [grok](), [harness](), [openai](), [openssl](), [v8](), [vulnerabilities]() ### AI overview SecPRBench evaluates agentic security review on 265 validated, real-world bug-introducing changes from nine critical systems, including Firefox, V8 and OpenSSL. Across eight frontier models, recall ranged from 32.5% to 78.1%, with Grok 4.6 and GPT-6 sol at the top. In 68% of misses, agents identified the file containing the flaw but proposed a different mechanism. Harness choice also changed results: OpenAI's Codex Security reduced recall by 8.3 points, mostly through abstention, while Anthropic's Defending Code increased it by 7.7 points at higher cost. ### Source excerpt arXiv:2610.33509v1 Announce Type: cross Abstract: LLM agents have been increasingly adopted for security-focused code review, but existing benchmarks mostly derive the reviewed changes from their later fixes instead of the real-world bug-introducing commits. In this paper, we present SecPRBench, the first comprehensive benchmark for evaluating agentic security review on validated real-world code changes. More specifically, we have built an automated agentic pipeline to autonomously harvest, build, and validate massive real-world bug-introducing commits for popular software systems. To ensure precise evaluation, we also adopt LLM-as-a-judge to credit the findings matching ground-truth vulnerabilities. To date, we have collected 265 tasks from nine critical systems, including Firefox, V8, and OpenSSL with millions of lines of code. Across eight frontier models, recall ranges from 32.5% to 78.1%, with Grok 4.6 and GPT-6 sol ranking at the top. Our study also shows that most misses are not simply oversights: in 68% of them, the agent reports on a file that holds the flaw but argues for a different mechanism. Security-focused harnesses also behave differently: OpenAI's Codex Security lowers recall by 8.3 points, mostly by abstaining, while Anthropic's Defending Code harness raises it by 7.7 points, at a higher cost. ## Electron 45 DevFeed: [Electron 45]() Original publisher: [Read original article]() Author: ckerr Published: 2026-10-21T00:00:00Z Content type: release Language: en Sources: [Electron Blog]() Topics: [Electron](), [Chromium](), [npm](), [AI Chat]() Tags: [1password](), [ai](), [api](), [c-plus-plus](), [chromium](), [crash-reporting](), [electron](), [node](), [release](), [upgrades](), [v8]() ### AI overview Electron 45 updates Chromium to 156.0.8078.48, V8 to 15.6, and Node.js to v24.22.0, with performance improvements to startup, menus, native API calls, and reads from ASAR archives. Key migration work includes replacing removed Node.js shims and globals in sandboxed preloads, allowing the new `display-capture` permission for screen sharing, and adapting code that uses raw file descriptors from ASAR files. The release adds experimental local Prompt API integration, which requires the application to provide its own model and inference implementation, and macOS platform passkeys through Apple's native credential sheet. Windows crash reporting gains coverage for some failures that bypass the in-process handler; package the matching WER helper DLL alongside the executable. Native heap profiling now uses Perfetto, profiles C/C++ allocations rather than JavaScript memory, and recordings use protobuf format. Electron 42 is end of support. ### Source excerpt Electron 45 has been released! It includes upgrades to Chromium 156.0.8078.48, V8 15.6, and Node v24.22.0. ## Researchers used GPT-5.6 Sol to find Chrome sandbox escape vulnerabilities DevFeed: [Researchers used GPT-5.6 Sol to find Chrome sandbox escape vulnerabilities]() Original publisher: [Read original article]() Author: Maxwell Cooter Published: 2026-10-16T15:14:59Z Content type: news Language: en Sources: [Computerworld]() Topics: [Docro Hijacker](), [BlueMoon](), [V8](), [Windows]() Tags: [ai](), [browser](), [browser-security](), [browser-security-browsers-chrome-endpoint-protection-productivity-software-security-vulnerabil](), [browsers](), [bug](), [bug-bounty](), [chrome](), [code](), [edition-us](), [endpoint-protection](), [exploit](), [gpt](), [gpt-5](), [language-en](), [news-brief](), [productivity-software](), [sandbox](), [search](), [security](), [source-code](), [storytype-news](), [take](), [test](), [used](), [v8](), [vulnerabilities](), [vulnerability](), [windows]() ### AI overview Researchers at Xbow used OpenAI's GPT-5.6 Sol to search Chrome's source code, test ideas, and build proofs of concept. Over six days and $40,000 in AI compute, they chained vulnerabilities that could escape Chrome's V8 and operating-system sandboxes, earning a $250,000 Google bug bounty. Google fixed the flaws. ### Source excerpt A chain of vulnerabilities in Google's Chrome browser could have enabled researchers to take control of one billion Windows machines worldwide -- and it cost them just $40,000 in AI compute time to discover it. Researchers at Xbow USA worked for six days on developing the exploit, which earned them a $250,000 bug bounty from Google, the first under the new 2026 rules. They chose OpenAI's GPT-5.6 Sol for the task to demonstrate what's possible with a publicly available model rather than a specialist security implementation. They used it to search Chrome's source code, test ideas, and build proofs of concept, while they set the strategy, chose where to look, and checked its work. They successfully chained together a vulnerability to escape first from the sandbox containing the V8 JavaScript engine and then from Chrome's operating-system process sandbox, launching a Windows app from within a malicious web page. Xbow presented its findings to Google, which fixed the flaws. The researchers set out all the details as to how the exploit was developed in a blog. ## Pulumi Google Cloud Provider Version 10.0.0 DevFeed: [Pulumi Google Cloud Provider Version 10.0.0]() Original publisher: [Read original article]() Author: Alberto Pose Published: 2026-10-06T15:00:00Z Content type: release Language: en Sources: [Pulumi]() Topics: [Google Cloud Platform (GCP)](), [pulumi-cli](), [Agent Skills]() Tags: [agent-skills](), [features](), [google-cloud](), [product](), [pulumi](), [releases](), [v8]() ### AI overview Pulumi released version 10 of its Google Cloud provider, based on version 8 of terraform-provider-google. The release includes a migration guide and an updated provider-upgrade skill that can scan project code and infrastructure, explain affected resources, and help prepare an upgrade. The article also highlights new support for Google Cloud TPU and Vertex AI resources. ### Source excerpt TL;DR: we are releasing a new major version of the Google Cloud provider. To migrate, ask Neo or your coding agent to run the Pulumi provider-upgrade skill (how to use it) or follow the v10 migration guide. We are happy to announce the next major version of the Pulumi Google Cloud provider. This release is based on the new v8 major version of terraform-provider-google (see also the upstream v8 upgrade guide). It ships with a migration guide that covers every breaking change in depth. Here are a few links to help you get started if you are new to Pulumi: Getting Started: a guided walkthrough for creating your first project Setup & Install: how to install the Google Cloud provider How-to guides: how to provision specific resources with the Google Cloud provider Pulumi Neo: ask Pulumi Neo to help you with your project Upgrading The migration guide accounts for every resource, type and function that changed in the new version. For the most popular resources, it gives a description of the change, a risk and impact section, a way to check whether you are affected, and step by step migration snippets. Use an agent to assist with your upgrade We have updated the provider-upgrade skill in Pulumi Agent Skills to cover the upgrade from v9. You can use it from Pulumi Neo or from any popular coding agent. Before it bumps the provider, it scans your stack and code for the changes that affect you, and it stops to ask before anything that would replace or delete live infrastructure. Then it upgrades the dependency, runs pulumi preview until the diff is explained, and leaves pulumi up to you. In Neo, ask: "Upgrade this project to pulumi-gcp v10." Neo picks the provider-upgrade skill for you; there is nothing to install or name. Neo plans the upgrade, starting with a scan of your stack while it is still on v9. Before it edits any code, it tells you which resources are affected and what could be replaced, and waits for your answer. Finally, Neo opens a pull request with the changes an ## Node.js 22.23.3 (LTS) DevFeed: [Node.js 22.23.3 (LTS)]() Original publisher: [Read original article]() Published: 2026-09-23T18:22:40Z Content type: release Language: en Sources: [Node.js]() Topics: [Node.js](), [JavaScript](), [openssl](), [Open Source](), [V8]() Tags: [ed25519](), [esm](), [http2](), [javascript](), [lts](), [node-js](), [npm](), [open-source](), [openssl](), [test](), [v8](), [windows]() ### AI overview Node.js 22.23.3 is an LTS release containing dependency upgrades and maintenance updates, including newer npm, OpenSSL, Corepack, ICU, Undici, c-ares, and timezone data.

The platform runs Python through Pyodide-compiled WebAssembly in the V8-based workerd runtime, with limitations including non-functional multiprocessing and threading. Its local development tool simulates the stack using a 123MB binary. ### Source excerpt Cloudflare Python Workers are now generally available After a two year preview, Cloudflare's support for running Python code in their server-side Workers platform is now stable: "Python is now a first-class, fully supported language on the Cloudflare Developer Platform". A neat thing about this is how it works. Cloudflare are running Python compiled to WebAssembly via Pyodide in their V8-based workerd runtime. This comes with some limitations, documented here - most notably both multiprocessing and threading are non-functional in the WebAssembly VM. One particularly interesting detail of this is the local development environment story - their pywrangler development tool (confusingly packaged as workers-py on PyPI) runs a full local simulation of their stack, including executing code with Pyodide in WebAssembly in V8 in a 123MB workerd binary, which for me ended up in node_modules/@cloudflare/workerd-darwin-arm64/bin/workerd. Python Workers represent a significant investment in the wider Python ecosystem by Cloudflare. The release announcement is credited to Gyeongjae Choi, Dominik Picheta, and Hood Chatham - Gyeongjae and Hood are both Pyodide core maintainers.

After decompressing the JSC files, a version-compatible V8 disassembler and modified View8 produce pseudocode; successive passes propagate values, reconstruct RC4-protected strings, unflatten control flow, and resolve proxy and operation wrappers. The authors report analyzable output for 23 samples, while noting that compilation is lossy and some complex control-flow variants may remain unresolved. An optional LLM stage suggests function names to aid navigation; the authors treat those names as hypotheses to verify against code, strings, APIs, paths, and data flow. In one sample, recovered code showed browser credential and cookie theft, automated Google session replay, keylogging and screenshot capture, and a local HTTPS interception proxy with service-specific traffic modification. The excerpt also notes newer payload encryption and macOS targeting. ### Source excerpt Research by: hasherezade Key Points Introduction JSCeal is a stealer delivered as compiled V8 bytecode (.jsc) and executed by a bundled Node.js runtime, targeting cryptocurrency applications (other vendors also tag it with the names WEEVILPROXY or MeadowLocust).

The clipboard API is now asynchronous and W3C-aligned; renderer processes must use `navigator.clipboard` or narrowly expose needed helpers through `contextBridge`. Breaking changes include requiring macOS 13 or later, dropping 32-bit Windows and Linux ARM builds, and statically linking ANGLE so applications can no longer replace its shipped libraries. Apps handling `select-client-certificate` must allow for a null `webContents`; `net.request` also rejects frame destinations unless the fetch mode is `navigate`. The release adds APIs including main-process `net.WebSocket`, per-content zoom controls, and frame-level PDF printing, alongside startup and runtime performance improvements. ### Source excerpt Electron 44 has been released! It includes upgrades to Chromium 152.0.7977.54, V8 15.2, and Node v24.18.1. ## Kitesurf: Cloudflare's Agent-First Browser Runs in V8 Isolates on Workers DevFeed: [Kitesurf: Cloudflare's Agent-First Browser Runs in V8 Isolates on Workers]() Original publisher: [Read original article]() Author: Developers Digest Published: 2026-08-06T00:00:00Z Content type: release Language: en Sources: [Developers Digest]() Topics: [Cloudflare](), [browser](), [Rust](), [V8](), [WebAssembly](), [Chromium]() Tags: [agent](), [agents](), [beta](), [browser](), [browser-automation](), [chromium](), [cloudflare](), [compatibility](), [cpu](), [free](), [memory](), [news](), [rendering](), [run](), [rust](), [v8](), [webassembly](), [workers]() ### AI overview Cloudflare shipped Kitesurf, an agent-first browser running entirely on Workers. It uses Rust and WebAssembly rendering, per-page isolates, and CDP compatibility, and is described as using 3-7 times less memory and CPU than Chromium for common agent tasks. It is free in beta through Browser Run. ### Source excerpt Cloudflare shipped Kitesurf, an agent-first browser that runs entirely on Workers: Rust and WebAssembly rendering, per-page isolates, CDP compatibility, and 3-7x less memory and CPU than Chromium for common agent tasks.

It describes their serverless V8 execution model, per-object SQLite storage, ID-based request routing, event-driven structure, and potential shortcomings. ### Source excerpt I've spent the last few months building almost exclusively on Cloudflare Durable Objects. They're a near-perfect primitive for building agents--here's where they shine, and where they fall short. ## Electron 43 DevFeed: [Electron 43]() Original publisher: [Read original article]() Author: jkleinsc Published: 2026-07-02T00:00:00Z Content type: release Language: en Sources: [Electron Blog]() Topics: [Electron](), [app startup](), [performance-optimization]() Tags: [chromium](), [electron](), [node](), [release](), [upgrades](), [v8]() ### AI overview Electron 43 upgrades Chromium to 150.0.7871.46, Node.js to v24.17.0, and V8 to 15.0. Startup improvements use an embedded Node.js snapshot, cached V8 bytecode for framework bundles and preload scripts, and renderer startup data sent before navigation. Behavior changes include rounded corners by default for frameless Linux windows (disable with `roundedCorners: false`), downloads opening in Downloads or Home, and `nativeImage` pixels being normalized to sRGB. macOS adds notification history and removal APIs; Linux Window Controls Overlay follows native title bar layout, so apps should keep title content within the documented safe area. The Linux `dialog` API no longer supports `showHiddenFiles`. Electron 43 is the final series with prebuilt Windows x86 and Linux ARM 32-bit binaries; support ends after v43 reaches end of life in January 2027. ### Source excerpt Electron 43 has been released!

It covers the build process, runtime modules, binary size, dependencies, and initial performance observations. ### Source excerpt Hear ye, hear ye: Wastrel and Hoot means REPL! Which is to say, Wastrel can now make native binaries out of WebAssembly files as produced by the Hoot Scheme toolchain, up to and including a full read-eval-print loop. Like the REPL on the Hoot web page, but instead of requiring a browser, you can just run it on your console. Amazing stuff! try it at home First, we need the latest Hoot. Build it from source, then compile a simple REPL: echo '(import (hoot repl)) (spawn-repl)' > repl.scm ./pre-inst-env hoot compile -fruntime-modules -o repl.wasm repl.scm This takes about a minute. The resulting wasm file has a pretty full standard library including a full macro expander and evaluator. Normally Hoot would do some aggressive tree-shaking to discard any definitions not used by the program, but with a REPL we don't know what we might need. So, we pass -fruntime-modules to instruct Hoot to record all modules and their bindings in a central registry, so they can be looked up at run-time. This results in a 6.6 MB Wasm file; with tree-shaking we would have been at 1.2 MB. Next, build Wastrel from source, and compile our new repl.wasm: wastrel compile -o repl repl.wasm This takes about 5 minutes on my machine: about 3 minutes to generate all the C, about 6.6MLOC all in all, split into a couple hundred files of about 30KLOC each, and then 2 minutes to compile with GCC and link-time optimization (parallelised over 32 cores in my case). I have some ideas to golf the first part down a bit, but the the GCC side will resist improvements. Finally, the moment of truth: $ ./repl Hoot 0.8.0 Enter `,help' for help. (hoot user)> "hello, world!" => "hello, world!" (hoot user)> statics When I first got the REPL working last week, I gasped out loud: it's alive, it's alive!!! Now that some days have passed, I am finally able to look a bit more dispassionately at where we're at. Firstly, let's look at the compiled binary itself. By default, Wastrel passes the -g flag to GCC, which results in bi ## Electron 41 DevFeed: [Electron 41]() Original publisher: [Read original article]() Author: ckerr; nmggithub Published: 2026-03-10T00:00:00Z Content type: release Language: en Sources: [Electron Blog]() Topics: [Electron](), [releases](), [Chromium](), [Node.js](), [V8](), [Security](), [Wayland]() Tags: [announce](), [chromium](), [electron](), [linux](), [macos](), [node](), [npm](), [release](), [security](), [upgrades](), [v8]() ### AI overview Electron 41 updates Chromium, V8, and Node.js, and recommends version 41.0.2 after high-priority bugs were addressed in patch releases.
