Anyone running BIG-IP (especially with APM access policies or APM as an OAuth authorization server), F5OS, BIG-IQ or end-of-support F5 hardware. - Do you run any of these? Adobe Experience Manager (AEM) Forms. They are being exploited in the wild (CISA KEV). Patch or mitigate if you do; CISA’s federal deadline is 2025-11-05. - npm: 1 critical advisory ( happy-dom ). Check with npm audit (or: npm ls ) . - None of it touches your stack? Then there is nothing to do today. That is a result, not a failure to read carefully. ## Editorial briefs - **Patch this week** [F5 Breach: Nation-State Stole BIG-IP Source Code](https://erroneo.us/security/briefs/f5-big-ip-source-code-breach/index.md): The breach itself needs no new action a year on, but its aftermath does: two unauthenticated BIG-IP APM RCEs are now on CISA's exploited list, so every BIG-IP owner should be on current fixed builds with management interfaces off the internet. ## Known exploited (CISA KEV) - [CVE-2025-54253](https://erroneo.us/security/cve/CVE-2025-54253/index.md) Adobe Experience Manager (AEM) Forms: Adobe Experience Manager Forms Code Execution Vulnerability (CISA due 2025-11-05) ## Critical advisories - [CVE-2025-62410](https://erroneo.us/security/cve/CVE-2025-62410/index.md) happy-dom's `--disallow-code-generation-from-strings` is not sufficient for isolating untrusted JavaScript — npm happy-dom >= 19.0.0, < 20.0.2 → 20.0.2 --- Source page: https://erroneo.us/security/2025-10-15/ · Security Digest: https://erroneo.us/security/ · More: https://erroneo.us/llms.txt
