Critical (9.3) in F5 BIG-IP APM. In CISA KEV since 2026-09-22. EPSS 27% chance of exploitation in the next 30 days.
When a BIG-IP APM access policy and an OAuth profile are configured on a virtual server, specific malicious traffic can lead to remote code execution (RCE). This vulnerability is only present when BIG-IP APM is configured as an OAuth Authorization Server. Deployments using APM strictly as an OAuth Client / Resource Server (without OAuth authorization server profiles configured) are not affected by this vulnerability.
Impact:
This vulnerability allows an unauthenticated attacker to perform remote code execution. The BIG-IP system in Appliance mode is also vulnerable. This is a data plane issue; there is no control plane exposure.
Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
