It says models should remain replaceable, while organizations take responsibility for operating inference: F5 research cited reports 78% run inference themselves across an average of seven models, while 2% were equipped to operate AI at scale a year earlier. The article describes growing reliability and security challenges as agent workflows lengthen, and recommends inventorying production infrastructure and chain performance, budgeting performance, security, and governance together, and using a platform approach to apply policies consistently across models and hybrid multicloud environments. It presents F5 ADSP as one such platform. ### Source excerpt As organizations incorporate AI into their environments, they're hyper-focused on the AI model. Many executives I talk to spend a lot of time considering what model they should purchase from which vendor. They're also concerned about which use case they should implement first. Yet the reality is that AI models are swappable components. The vast majority of organizations are using multiple AI models, switching them out for their specific needs based on cost, accuracy, and security. It's the right thing to do; organizations with architectures that make it difficult to swap out AI models are making the wrong bet. What can't be swapped out is your inference path--or everything that happens between a user's intent and the model's output. This includes the retrieval layer that decides what context the model sees. It includes the routing logic that chooses what model handles which request. It includes the identity that travels with the call. And it includes your organization's policies, which decide what the model can do with the answer. That is where accuracy and costs are determined. It's also where your proprietary advantage lies. A competitor can buy the same model you have, but they cannot buy your inference path, which determines not only the quality and cost of AI, but also its performance, resilience, and security at scale. Adoption of AI inference is outpacing readiness That truth is becoming increasingly important as AI adoption continues to accelerate. Recent F5 research found that more than three of every four organizations (78%) now run AI inference themselves across an average of seven AI models. Yet our research from a year ago found that just 2% of organizations were genuinely equipped to operate AI at scale. What this shows is that enterprises are taking inference in-house, even when they're not ready, because they want their data, expenses, and security posture under their own roof. All of this makes sense. But taking inference in-house also means taking r ## F5 releases out-of-band patches for critical NGINX vulnerabilities DevFeed: [F5 releases out-of-band patches for critical NGINX vulnerabilities]() Original publisher: [Read original article]() Author: Sergiu Gatlan Published: 2026-10-19T13:49:24Z Content type: news Language: en Sources: [BleepingComputer]() Topics: [nginx](), [patches](), [Vulnerabilities](), [Security research]() Tags: [code-execution](), [computer-help](), [computer-security](), [computers](), [critical](), [denial-of-service](), [dos](), [f5](), [infosec](), [infosec-computer-security](), [linux](), [mac](), [malware](), [malware-removal](), [nginx](), [out-of-band](), [patches](), [rce](), [remote-code-execution](), [security](), [spyware](), [support](), [tech-support](), [technical-support](), [virus](), [virus-removal](), [vulnerabilities](), [vulnerability](), [windows]() ### AI overview F5 released out-of-band patches for multiple NGINX products addressing several vulnerabilities, including three critical flaws that may allow remote attackers to cause denial of service or execute code under specified conditions.

The heap-based buffer overflow affects deployments configured as OAuth authorization servers, and CISA added it to the Known Exploited Vulnerabilities catalog. F5 provided hotfixes and an interim iRule mitigation. ### Source excerpt Technology company F5 fixed a critical remote code execution vulnerability in its BIG-IP Access Policy Manager (APM) platform on Tuesday. The flaw impacts deployments configured as OAuth authorization servers and was already under active exploitation in the wild before the patch became available. BIG-IP APM is a software component in F5's BIG-IP hardware platform that enables companies to control access to internal network resources. APM performs various client-side checks and handles authorization and authentication, along with providing VPN connectivity for remote users. The flaw, tracked as CVE-2026-94127, is described as a heap-based buffer overflow and is rated 9.8 on the CVSS scale. The vulnerability impacts the BIG-IP system when configured in appliance mode as well but can be exploited only when both APM and an OAuth authorization server profile are configured. Deployments using APM only as an OAuth client or resource server are not affected, F5 said in its advisory. The company advises users to apply Hotfix-BIGIP-21.1.0.2.0.30.22-ENG.iso for the 21.x for the 21.x release branch and Hotfix-BIGIP-17.5.1.9.0.160.12-ENG.iso or Hotfix-BIGIP 17.1.3.5.0.41.14-ENG.iso for the still supported 17.5.x and 17.1.x branches. In addition to the fixes, F5 also released an iRule that can be obtained from the support portal and can be deployed as mitigation until the patch gets applied. Check for OAuth failures The US Cybersecurity and Infrastructure Security Agency (CISA) added this vulnerability to its Known Exploited Vulnerabilities (KEV) catalog on Tuesday, signaling confirmed active exploitation in the wild. The Shadowserver Foundation tracks more than 15,000 BIG-IP APM deployments exposed to the internet, with North America and Europe accounting for around 5,000 each. F5 advises customers to check installations for several indicators of compromise that require correlation as the presence of just one is not necessarily a sign of exploitation.

The article identifies affected release trains, fixed hotfixes, CISA KEV inclusion, and mitigation guidance. ### Source excerpt Overview On September 22, 2026, F5 published a security advisory for CVE-2026-94127, a critical heap-based buffer overflow vulnerability affecting F5 BIG-IP Access Policy Manager (APM). The vulnerability has a CVSS v3.1 score of 9.8. An unauthenticated attacker with network access to an affected virtual server may be able to achieve remote code execution (RCE) by sending specifically crafted traffic. BIG-IP APM provides identity-aware access control for applications and other corporate resources and can integrate with authentication technologies including OAuth, OpenID Connect, and SAML. CVE-2026-94127 is not exposed in a default configuration: exploitation requires a BIG-IP virtual server with both an APM access policy and an OAuth profile configured. Because affected BIG-IP systems may process traffic at an organization's network edge, organizations using this configuration should prioritize remediation. The vulnerability affects the data plane and does not expose the BIG-IP control plane. BIG-IP systems operating in Appliance mode are also affected. F5 lists the following affected release trains and corresponding fixed hotfixes: BIG-IP 21.1.0: versions prior to Hotfix-BIGIP-21.1.0.2.0.30.22-ENG BIG-IP 17.5.0: versions prior to Hotfix-BIGIP-17.5.1.9.0.160.12-ENG BIG-IP 17.1.0: versions prior to Hotfix-BIGIP-17.1.3.5.0.41.14-ENG As of September 22, 2026, CVE-2026-94127 has been added to the CISA KEV while a publicly available proof of concept was not confirmed. Mitigation guidance Organizations running affected F5 BIG-IP deployments should apply the appropriate F5 hotfix as soon as operationally feasible, particularly where a vulnerable APM and OAuth configuration is reachable from untrusted networks. F5 lists the following remediation versions: BIG-IP 21.1.0: update to Hotfix-BIGIP-21.1.0.2.0.30.22-ENG or later. BIG-IP 17.5.0: update to Hotfix-BIGIP-17.5.1.9.0.160.12-ENG or later. BIG-IP 17.1.0: update to Hotfix-BIGIP-17.1.3.5.0.41.14-ENG or later.

It successively narrows results using the `http.component:"Atlassian Confluence"` query, the `JSESSIONID` response cookie, a login-page HTML snippet, and repeated identical session IDs found in honeypots. The author estimates this leaves about 4,200 likely real hosts, while acknowledging they could instead be exceptionally convincing honeypots. Filtering by favicon is unreliable because legitimate users can upload their own, and Shodan offers no good way to exclude hosts without one. The example illustrates why exposed-host counts need validation before being treated as estimates of vulnerable installations. ### Source excerpt VulnCheck faces a horde of honeypots while assessing the potential impact of Atlassian Confluence's CVE-2023-22527. This blog delves into Shodan queries to filter out honeypots and uncover the actual on-premise Confluence install base. ## What is Backoff For? DevFeed: [What is Backoff For?]() Original publisher: [Read original article]() Author: Marc Brooker Published: 2022-08-11T00:00:00Z Content type: article Language: en Sources: [Marc Brooker's]() Topics: [rate-limiting](), [Server](), [Algorithms]() Tags: [adaptive](), [clients](), [customers](), [exponential-backoff](), [f5](), [flash](), [fleet](), [jitter](), [network](), [operational](), [popular](), [queue](), [recovery](), [reduce](), [serial](), [system](), [systems](), [website]() ### AI overview Backoff smooths short overload spikes by spreading requests over time; jitter helps broaden those spikes. During sustained overload, delaying requests only helps overall when it reduces total work. With many independent clients, backoff does not reduce first tries, and retry backoff mainly defers retry traffic rather than reducing its total amplification. With a bounded set of serial workers, backoff can reduce both retries and future first tries because each worker waits for its current request. The text recommends combining backoff and jitter with a sound retry policy, such as the token bucket based adaptive strategy it references. Its simulations report little effect from per-request backoff with unbounded clients, but substantial benefits with limited serial clients. The excerpt ends before the article's footnotes. ### Source excerpt What is Backoff For? Back off man, I'm a scientist. Years ago I wrote a blog post about exponential backoff and jitter, which has turned out to be enduringly popular. I like to believe that it's influenced at least a couple of systems to add jitter, and become more stable. However, I do feel a little guilty about pushing the popularity of jitter without clearly explaining what backoff and jitter do, and do not do. Here's the pithy statement about backoff: Backoff helps in the short term. It is only valuable in the long term if it reduces total work. Consider a system that suffers from short spikes4 of overload. That could be a flash sale, top-of-hour operational work, recovery after a brief network partition, etc. During the overload, some calls are failing, primarily due to the overload itself. Backing off in this case is extremely helpful: it spreads out the spike, and reduces the amount of chatter between clients and servers. Jitter is especially effective at helping broaden spikes. If you want to see this in action, look at the time series in the exponential backoff and jitter post. Now, consider a long spike of overload. There are two cases here. One is where we have a large (maybe effectively unlimited) number of clients, and they're independently sending work. For example, think about a website with a million customers, each visiting it about once a day. Each client backing off in this case does not help, because it does not reduce the work being sent to the system. Each client is still going to press F5 the same number of times, so delaying their presses doesn't help. The other is where we have a smaller number of clients, each sending a serial stream of requests. For example, think of a fleet of workers polling a queue. Each client backing off in this case helps a lot because they are serial. Backing off means they send less work, and less is asked of the service1. That may sound like a subtle distinction, but the bottom line is this: does backoff actually ## Stay in sync with GitHub for Windows DevFeed: [Stay in sync with GitHub for Windows]() Original publisher: [Read original article]() Author: Markus Olsson Published: 2013-10-25T00:28:16Z Content type: release Language: en Sources: [GitHub Blog]() Topics: [GitHub](), [Windows]() Tags: [branch](), [changes](), [commits](), [communication](), [compute](), [f5](), [github](), [latest](), [local](), [news-insights](), [release](), [remote](), [sync](), [syncing](), [the-library](), [update](), [windows]() ### AI overview GitHub for Windows now shows how many commits a local branch is ahead of or behind its remote beside the sync button. It updates that count automatically, or users can press F5 to refresh it. The sync button can also fetch the remote's latest changes at any time, even before the app detects them. ### Source excerpt Today we released an update to GitHub for Windows allowing you to quickly see when a branch is no longer in sync with its remote. Right next to the sync... ## Getting started with macOS VoiceOver DevFeed: [Getting started with macOS VoiceOver]() Original publisher: [Read original article]() Author: Mat Marquis Published: 2013-01-14T00:00:00Z Content type: tutorial Language: en Sources: [The A11Y Project]() Topics: [Web Accessibility (a11y)](), [macOS](), [Web]() Tags: [accessibility](), [all](), [allows](), [apple](), [arrow](), [automatically](), [based](), [basic](), [can](), [command](), [commands](), [content](), [control](), [documentation](), [elements](), [f5](), [getting](), [getting-started](), [macos](), [with]() ### AI overview macOS VoiceOver reads page content aloud and offers keyboard navigation that can help test accessibility. Turn it on with Command + F5, then press VO + F8 to open preferences; VO means Control + Option. Web navigation offers two modes: "grouping items" groups related content as rendered, letting you drill into lists with the down arrow and move in any direction with arrow keys. "DOM order" follows the page markup, enters lists automatically, and moves between DOM elements with left and right arrows; up and down follow the last method used in the Web Item Rotor. Open the rotor with VO + U to jump among links, headings, form controls, tables, web spaces, and ARIA landmarks. ### Source excerpt VoiceOver is the assistive software built into macOS. It provides a richer set of keyboard shortcuts for navigating a website and reads sections of the page aloud based on the current focus. It's a great way to test the accessibility of a project because it's always readily at-hand: you can toggle VoiceOver on/off by: Toggling it to "on" under "Universal Access" in your system preferences. Pressing Command + F5 Turning on VoiceOver enables a number of navigational key commands, all of which are performed by pressing Control and Option. This is usually abbreviated to "VO" in Apple's documentation (so VO + F1 means Control + Option + F1). To start out, try turning on VoiceOver with Command + F5, then use VO + F8 to open VoiceOver's preferences window--here you can adjust things like the voice used, speaking speed, and under "web": your navigation method. Navigation modes There are two modes you can use when navigating with VoiceOver: by "grouping items" or by "DOM order." These two methods allow you to interact with a page's content in slightly different ways. Grouping items Grouping items will flag that you are currently focused on a list, and you can begin interacting with the items by pressing the down arrow to "drill down" into those items. This mode attempts to group related content based on how the page is being rendered, and navigating by group will allow you to use the arrow keys to move in any direction. We'll be focusing on this mode. DOM Order DOM Order will flag that you are entering a list of items, and drill down into those items automatically. This mode is based entirely on the page's underlying markup. Navigating by DOM order allows you to shift focus between DOM elements with the left and right arrow keys. The up and down arrow keys are based on the last used navigation method in the "Web Item Rotor." Reading text Here are some basic interaction and navigation commands for VoiceOver.
