CERT-FR has published an advisory concerning a remote code execution vulnerability affecting F5 BIG-IP Access Policy Manager (APM). The vulnerability, tracked as CVE-2026-94127, allows an attacker to achieve arbitrary code execution on affected systems. F5 has confirmed that the vulnerability is being actively exploited in the wild, making this an urgent patching priority for organizations running affected BIG-IP APM versions.
Affected versions include BIG-IP APM 17.1.x prior to 17.1.3 (without hotfix Hotfix-BIGIP-17.1.3.5.0.41.14-ENG.iso), 17.5.x prior to 17.5.1 (without hotfix Hotfix-BIGIP-17.5.1.9.0.160.12-ENG.iso), and 21.x prior to 21.1.0 (without hotfix Hotfix-BIGIP-21.1.0.2.0.30.22-ENG.iso). F5 has released indicators of compromise in its own security bulletin (K000162605) to help defenders identify exploitation attempts or successful compromise.
Defenders running BIG-IP APM should apply the vendor hotfixes immediately given confirmed active exploitation, and review the F5 bulletin for the referenced indicators of compromise to hunt for signs of prior compromise on their systems.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,445 reports from 149 sources, 666 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
