{"id":"BIT-nginx-gateway-2026-97205","summary":"NGINX ngx_http_core_module vulnerability","details":"NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_core_module module. 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.","aliases":["BIT-nginx-2026-97205","CVE-2026-97205"],"modified":"2026-10-21T12:11:26.429928178Z","published":"2026-10-21T08:54:19.423Z","database_specific":{"severity":"Critical","cpes":["cpe:2.3:a:f5:nginx:*:*:*:*:*:*:*:*"]},"references":[{"type":"WEB","url":"https://my.f5.com/manage/s/article/K000162608"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-97205"}],"affected":[{"package":{"name":"nginx-gateway","ecosystem":"Bitnami","purl":"pkg:bitnami/nginx-gateway"},"ranges":[{"type":"SEMVER","events":[{"introduced":"1.30.0"},{"fixed":"1.30.6"},{"introduced":"1.31.0"},{"fixed":"1.31.7"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/nginx-gateway/BIT-nginx-gateway-2026-97205.json"},"severity":[{"type":"CVSS_V4","score":"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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}],"schema_version":"1.9.0"}
