When asynchronous file I/O (AIO) is enabled in certain configurations, processing a Server Side Includes (SSI) page containing “include virtual” commands may trigger a Use-After-Free (UAF) in the NGINX worker process. This may cause memory corruption or a worker process crash. Additionally, attackers can execute code on systems with Address Space Layout Randomization (ASLR) disabled or when the attacker can bypass ASLR.\n\nImpact:\nThis vulnerability may allow remote attackers to cause a denial-of-service (DoS) on the NGINX system, corrupt its memory, or possibly trigger code execution. There is no control plane exposure; this is a data plane issue only.\n\n\n\n\nNote: Software versions which have reached End of Technical Support (EoTS) are not evaluated.","state":0,"publishedAt":"2026-10-14T14:40:27.487+00:00","modifiedAt":"2026-10-15T10:31:15.547+00:00","affected":[{"ecosystem":"Vendor product","name":"NGINX Plus","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unknown\",\n                    \"modules\": [\n                        \"ngx_http_core_module\"\n                    ],\n                    \"product\": \"NGINX Plus\",\n                    \"vendor\": \"F5\",\n                    \"versions\": [\n                        {\n                            \"lessThan\": \"37.1.0.1\",\n                            \"status\": \"affected\",\n                            \"version\": \"37.1.0\",\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"lessThan\": \"37.0.5.1\",\n                            \"status\": \"affected\",\n                            \"version\": \"37.0.0\",\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"lessThan\": \"*\",\n                            \"status\": \"affected\",\n                            \"version\": \"R36\",\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"lessThan\": \"*\",\n                            \"status\": \"affected\",\n                            \"version\": \"R35\",\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"lessThan\": \"*\",\n                            \"status\": \"affected\",\n                            \"version\": \"R34\",\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"lessThan\": \"*\",\n                            \"status\": \"affected\",\n                            \"version\": \"R33\",\n                            \"versionType\": \"custom\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"NGINX Open Source","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"modules\": [\n                        \"ngx_http_core_module\"\n                    ],\n                    \"product\": \"NGINX Open Source\",\n                    \"vendor\": \"F5\",\n                    \"versions\": [\n                        {\n                            \"lessThan\": \"1.31.7\",\n                            \"status\": \"affected\",\n                            \"version\": \"1.31.0\",\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"lessThan\": \"1.30.6\",\n                            \"status\": \"affected\",\n                            \"version\": \"1.30.0\",\n                            \"versionType\": \"custom\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.1,"severity":"HIGH"},{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":9.2,"severity":"CRITICAL"}],"references":["https://my.f5.com/manage/s/article/K000162608"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-97205","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-97205","identifiers":["CVE-2026-97205"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
