PHP2Shell (CVE-2026-109618/109619) was exploited before patches appeared; applying the fix requires replacing the PHP runtime and restarting the web server, since old code otherwise stays in memory. Microsoft's emergency Brotli-related .NET fix covered .NET 8, 9, 10 and .NET 11 RC3; proof-of-concept code existed, but the article reported no known in-the-wild exploitation. Microsoft also removed seven compromised certificate entries from Windows trust and said preview fixes for VPN failures and Smart App Control would enter the November cumulative release. Apple's October updates addressed many CVEs, including a backported iOS/iPadOS fix for a CoreGraphics flaw reportedly exploited against targeted individuals. The November release expectations for Microsoft, Adobe, Google and Mozilla are forecasts, not confirmed releases. ### Source excerpt How did you enjoy October 2026 Patch Tuesday? Were there enough CVEs reported to keep you busy for the rest of the year or are you finished and ready for another round next week? They released the regularly scheduled update nearly two and a half hours late, but Microsoft did resolve another record-breaking 1,407 unique CVEs. As in previous months, there were limited CVEs we needed to immediately deal with. In October, one zero-day CVE-2026-96951 ...

The article presents AWS Elastic Beanstalk as a managed option that deploys existing applications, including Java, .NET Framework on IIS, PHP, and Python, without requiring every workload to be containerized. It provisions and maintains AWS resources while environments remain in the customer's AWS account, preserving visibility into identity, networking, security, and governance. The article says Elastic Beanstalk is HIPAA-eligible and in scope for AWS SOC, PCI, ISO, and FedRAMP reports, available through AWS Artifact. Its new Cluster Mode lets multiple applications share managed infrastructure and a common operational baseline; application code and dependency patching remain workload-specific. The case for this model is reducing operational drift and duplicated platform controls as portfolios grow, while retaining customer visibility. The excerpt emphasizes service continuity, but does not provide comparative performance, pricing, or implementation results. ### Source excerpt For more than a decade, the managed application platform industry has optimized around a compelling promise: get code running as The post AWS Elastic Beanstalk for regulated workloads: Built for the next decade, not just the first deploy appeared first on The New Stack. ## Microsoft's October Security Update Fixes 1,400+ Vulnerabilities, One Exploited in the Wild DevFeed: [Microsoft's October Security Update Fixes 1,400+ Vulnerabilities, One Exploited in the Wild]() Original publisher: [Read original article]() Author: Sergio De Simone Published: 2026-10-28T10:30:00Z Content type: news Language: en Sources: [InfoQ]() Topics: [known exploitable vulnerabilities](), [vulnerability management](), [Security](), [cve remediation](), [Deployment Strategies]() Tags: [2026](), [architecture-design](), [azure](), [critical](), [development](), [devops](), [edge](), [exchange](), [exploited](), [hyper-v](), [microsoft](), [microsoft-october-2026-patch](), [net](), [net-framework](), [news](), [october](), [office](), [os](), [security](), [security-update](), [security-vulnerabilities](), [shell](), [vulnerabilities](), [vulnerability](), [windows](), [windows-shell]() ### AI overview Microsoft's October update addresses 1,415 vulnerabilities across products including Windows, Office, Exchange, .NET and Edge; 85 are rated critical, and one Windows Shell flaw, CVE-2026-96951, is reported exploited in the wild. It can bypass Mark of the Web protections, but an attacker must persuade a user to open a crafted file or follow a link. The excerpt also notes that CVE-2026-108398 in .NET was publicly disclosed before the update, with no exploitation reported by Microsoft. Practitioners quoted in the source recommend prioritizing flaws rated above 9.0 and deploying patches in stages while monitoring for regressions. User reports describe KB5127648 disrupting WPA-Enterprise Wi-Fi and an update breaking IPSec VPN access on some laptops. ### Source excerpt Microsoft's latest monthly security update addresses 1415 vulnerabilities across multiple products. One vulnerability affecting Windows Shell has been exploited in the wild, while 85 are classified as critical. Affected products include Windows OS, Office, Exchange, .NET, Edge, as well as potentially Hyper-V and Azure components. By Sergio De Simone ## The 14 GB cold-start problem: Rebuilding self-hosted GitHub Actions runners on Azure Kubernetes Service DevFeed: [The 14 GB cold-start problem: Rebuilding self-hosted GitHub Actions runners on Azure Kubernetes Service]() Original publisher: [Read original article]() Author: Renicius Pagotto Fostaini Published: 2026-10-28T00:00:00Z Content type: article Language: en Sources: [Thoughtworks Insights]() Topics: [Azure Kubernetes Service](), [self-hosted runner](), [GitHub Actions](), [CI/CD](), [internal developer platform automation](), [platform engineering automation](), [Azure]() Tags: [actions](), [aks](), [arc](), [autoscaling](), [azure](), [azure-container-apps](), [azure-kubernetes-service](), [azure-virtual-machines](), [build](), [build-times](), [build-tools](), [cache](), [caching](), [capacity](), [cold-start-problem](), [github](), [github-actions](), [kubernetes](), [net-framework](), [self-hosted]() ### AI overview For this team, combining ephemeral Windows runners on Azure Kubernetes Service (AKS), GitHub Actions Runner Controller (ARC), cached container images and prebuilt toolchains reduced reported pipeline duration from about 40 minutes to 10-15 minutes. Serverless containers first enabled more parallel work and brought runs to about 30 minutes, but cold starts spent 5-10 minutes pulling a 14 GB image; on AKS, a cached pull reportedly took 10-20 seconds. The team separated lightweight runner coordination from scalable worker nodes, used off-hours scale-down, ephemeral OS disks and image garbage collection, and packaged reusable workflows for application teams. These results are specific to the implementation: scaling workers to zero can lose the cache and restore cold-start delays, while keeping warm capacity trades lower latency for idle cost. The excerpt also reports an approximately 66% compute-cost reduction (about $7,800 annualized), contingent on comparable measurement scope. AKS adds operational responsibilities; the article recommends measuring queue and end-to-end time, cold versus warm starts, costs, and behavior at configured concurrency limits. ### Source excerpt The 14 GB cold-start problem: Rebuilding self-hosted GitHub Actions runners on Azure Kubernetes Service ## .NET October 2026 Out-of-Band Security Updates DevFeed: [.NET October 2026 Out-of-Band Security Updates]() Original publisher: [Read original article]() Author: Rahul Bhandari (MSFT) Published: 2026-10-25T18:45:00Z Content type: release Language: en Sources: [.NET Blog]() Topics: [.NET](), [Security](), [ASP.NET Core]() Tags: [2026](), [algorithm](), [apis](), [application](), [applications](), [artifacts](), [brotli](), [cve-2026-111497](), [cve-2026-114148](), [maintenance-updates](), [net](), [net-10](), [net-11](), [net-8](), [net-9](), [net-framework](), [october](), [oob](), [out-of-band](), [ownership](), [security](), [security-updates](), [updates](), [vulnerability]() ### AI overview The October 2026 out-of-band updates for .NET 8, 9, and 10 and .NET 11 RC3 address Brotli decoder vulnerability CVE-2026-111497 and Linux tarball ownership vulnerability CVE-2026-114148, and provide fixes for two issues not fully addressed by the October 13 release. Brotli processing may be affected through ASP.NET Core request decompression, HttpClient automatic response decompression, or System.IO.Compression APIs; the two decompression features are off by default, and .NET Framework is unaffected. The tarball issue affects source-build tarballs for .NET 10 and 11, and also ASP.NET Core tarball distributions for .NET 8 and 9. To update, install the targeted runtime and restart framework-dependent apps; rebuild and republish self-contained apps; rebuild and redeploy containers with updated images; or use updated source-build artifacts and rebuild packages. ASP.NET Core tarball users on .NET 8 and 9 should install the refreshed tarball. .NET 11 RC2 users should move to RC3. ### Source excerpt Out-of-band security updates for .NET address the Brotli decoder vulnerability and tarball ownership vulnerability.

Publishing before the SQL commit can expose an event for rolled-back data; publishing afterward can leave committed data without an event. The outbox addresses this dual-write gap by recording the business change and outgoing message in one database transaction, then dispatching to RabbitMQ asynchronously with publisher confirms and retries. A crash after broker confirmation but before marking the outbox row can cause duplicate publication, so consumers need idempotent processing, such as storing MessageId with business updates in one transaction. This replaces coordinated distributed transactions with eventual consistency and at-least-once delivery. The article also outlines operational needs such as concurrent row claiming, backoff, ordering, poison-message handling, monitoring, and cleanup, and recommends isolating messaging changes from runtime migration. ### Source excerpt Learn why replacing transactional MSMQ with RabbitMQ changes consistency guarantees and how the outbox pattern helps preserve reliable messaging. TL;DR: Repla ## An introduction to Compact Binary Object Representation (CBOR) in .NET DevFeed: [An introduction to Compact Binary Object Representation (CBOR) in .NET]() Original publisher: [Read original article]() Author: Andrew Lock Published: 2026-10-20T10:00:00Z Content type: article Language: en Sources: [Andrew Lock | .NET Escapades]() Topics: [Data serialization](), [.NET](), [Decoding](), [JSON](), [Encoding](), [hex value](), [NuGet](), [system.text.json]() Tags: [api](), [apis](), [asp-net-core](), [base64](), [data-protection](), [data-serialization](), [introduction](), [json](), [net](), [net-10](), [net-11](), [net-core](), [net-framework](), [nuget](), [nuget-package]() ### AI overview CBOR offers a self-describing binary alternative to JSON, with native binary data, compact encodings for values such as small numbers, and support for indefinite-length collections that can help with streaming. Text payload sizes are roughly comparable to JSON, and actual savings depend on the data. The excerpt contrasts CBOR with Protobuf, which can be highly efficient but requires shared schemas, and MessagePack, which is similar but lacks CBOR's formal IETF standardization and streaming support as described here. In .NET, System.Formats.Cbor provides low-level CborWriter and CborReader APIs: callers write and read primitive values and manage structure themselves rather than automatically mapping objects. The examples cover encoding and decoding maps and arrays, selecting conformance modes such as canonical key ordering, and skipping unknown values for forward compatibility. The author suggests JSON remains suitable for most APIs and points to ASP.NET Core's use of CBOR for compact, application-specific cookie data. ### Source excerpt In this post I introduce CBOR as a JSON alternative, and show how to use the System.Formats.Cbor NuGet package to read and write CBOR encoded data ## Patch Tuesday - October 2026 DevFeed: [Patch Tuesday - October 2026]() Original publisher: [Read original article]() Author: Adam Barnett Published: 2026-10-13T21:40:27Z Content type: news Language: en Sources: [Rapid7 Cybersecurity]() Topics: [known exploitable vulnerabilities](), [Windows](), [.NET Framework]() Tags: [2026](), [assembly](), [bypass](), [cloud](), [cloud-services](), [cve](), [cve-2026-108398](), [cve-2026-96951](), [cybersecurity-company](), [defender](), [disclosure](), [exploitation](), [exploited](), [explorer](), [exposure-assessment-platform](), [exposure-management](), [feature](), [managed-detection-and-response](), [managed-security-solutions](), [net-framework](), [october](), [october-2026](), [patch](), [patch-tuesday](), [patch-tuesday-october-2026](), [vulnerability-management]() ### AI overview Microsoft's October 2026 Patch Tuesday publishes 1,413 product vulnerabilities, including 1,102 in Windows; the excerpt says Microsoft is aware of one exploited-in-the-wild flaw and public disclosure of two others. CVE-2026-96951 is an exploited Windows Shell security feature bypass that can suppress the Mark of the Web warning. Exploitation requires a user to open a specially crafted malicious file or visit an attacker-controlled site. Windows Server 2012 receives no patch, while Server 2012 R2 does; Outlook.com was patched weeks earlier. The excerpt also describes publicly disclosed .NET Framework flaw CVE-2026-108398, which requires an attacker to already have a foothold and register a malicious .NET assembly for loading by a protected process. The excerpt ends before describing the bypass further. ### Source excerpt Microsoft is publishing 1,413 own-product vulnerabilities on October 2026 Patch Tuesday, including 1,102 vulnerabilities in Windows. Anyone who enjoyed last month's record-setting Patch Tuesday will love the October 2026 edition, because it's much bigger still. As Rapid7 has noted over the course of 2026, there is every reason to suppose that vulnerability volumes will continue to rise. Microsoft is aware of exploitation in the wild for just one of the vulnerabilities published today, as well as public disclosure for two others. Windows Shell: zero-day security feature bypass The Windows Shell is Microsoft's term for the GUI interaction logic for the entire OS provided by explorer.exe and associated libraries and APIs, and for the second time this year, the Windows Shell is the site of an exploited-in-the-wild zero-day vulnerability. Today's specimen is CVE-2026-96951. Once again, the immediate prize for an attacker is a Mark of the Web (MOTW) bypass. What this means is that Windows won't provide the user with a dialog explaining that Windows protected their PC, because in this case, it didn't. Exploitation requires that a user opens a specially crafted malicious file or visits an attacker-controlled site, so the evergreen advice about being careful what you click remains valid. Fans of vintage operating systems should note that Windows Server 2012 doesn't receive a patch, although Server 2012 R2 does. The advisory acknowledges reporters from multiple organizations, although none from within Microsoft. The vulnerability also affected Microsoft's Outlook.com cloud services, although Outlook.com was patched in a build dated several weeks ago. .NET Framework: zero-day security feature bypass Microsoft is aware of some level of public disclosure of CVE-2026-108398, a .NET Framework security feature bypass. Exploitation requires an attacker with an existing foothold to register a malicious .NET assembly for loading by a protected process, bypassing Windows Defender Appli ## .NET and .NET Framework October 2026 servicing releases updates DevFeed: [.NET and .NET Framework October 2026 servicing releases updates]() Original publisher: [Read original article]() Author: Rahul Bhandari (MSFT), Tara Overfield Published: 2026-10-12T20:00:00Z Content type: release Language: en Sources: [.NET Blog]() Topics: [releases](), [.NET](), [.NET Framework]() Tags: [2026](), [maintenance-updates](), [net](), [net-framework](), [october](), [releases](), [security]() ### AI overview This post recaps October 2026 servicing updates for .NET and .NET Framework, including security and non-security fixes.
