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.
