CVE-2026-94127 is a heap-based buffer overflow in F5 BIG-IP Access Policy Manager (APM) OAuth processing. A vulnerable virtual server that has both an APM access policy and an OAuth profile configured can be reached with specially crafted network traffic, allowing an unauthenticated remote attacker to execute arbitrary code. The flaw is in the BIG-IP data plane and also affects Appliance Mode deployments; no control-plane exposure is stated. Affected releases include BIG-IP APM 21.1.0, 17.5.0 through 17.5.1, and 17.1.0 through 17.1.3 prior to the applicable engineering hotfixes. Active exploitation has been observed.
