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.\n\nImpact:\nThis 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.\n\n \n\n\nNote: Software versions which have reached End of Technical Support (EoTS) are not evaluated.","cvss_version":"3.1","cvss_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","base_score":9.8,"base_severity":"CRITICAL","attack_vector":"NETWORK","privileges_req":"NONE","user_interaction":"NONE","scope":"UNCHANGED","impact_c":"HIGH","impact_i":"HIGH","impact_a":"HIGH","cwe_ids":["CWE-122"],"in_kev":true,"kev_date_added":"2026-09-22","kev_ransomware":false,"epss_score":0.2655,"epss_percentile":0.98016,"cap_rule_version":"0.1.1","stage":"INITIAL_ACCESS","req_access":"NONE","req_vector":"NETWORK","req_user_interaction":false,"grant_access":"USER","caps":["CODE_EXEC"],"terminal":false,"cap_confidence":"high","ingested_at":"2026-10-07T07:15:54.533319+00:00","first_seen":"2026-09-23T03:16:59.109946+00:00","kev_first_seen":"2026-09-23T03:17:17.846717+00:00","novelty_score":56.52,"novelty_reasons":["EPSS_SPIKE","HIGH_LEVERAGE_STEPPING_STONE","REACHES_TERMINAL","RAISES_REACH_COMMON_PRODUCT"],"novelty_at":"2026-11-02T03:21:44.260683+00:00","vendors":["f5"],"products":["big-ip_access_policy_manager"],"affected":[{"vendor":"f5","product":"big-ip_access_policy_manager","ranges":["≥ 17.0.0 and ≤ 17.1.3","≥ 17.5.0 and ≤ 17.5.1","21.1.0"]}]}
