Prior to version 1.2.14, if a server received an HTTP/1.0 request without a header Host, which was permitted by HTTP core of Nginx, then r->headers_in.host was NULL, nginx-http-flv-module used r->headers_in.host->value to make a pseudo tcUrl, so NULL-pointer dereference happened. This issue has been patched in version 1.2.14.","epss":{"date":"2026-11-12","percentile":0.32159,"score":0.00377},"exploits":[],"kev":null,"metrics":[{"score":8.7,"severity":"high","source":"CNA: GitHub_M","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},{"score":8.7,"severity":"high","source":"NVD: security-advisories@github.com","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/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","version":"4.0"}],"modifiedAt":1794506103952,"publishedAt":1794431193886,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/winshining/nginx-http-flv-module/security/advisories/GHSA-8mc6-jrxv-29g9"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://www.chtsecurity.com/news/b15d7b24-0a5e-4962-8b52-e4754e5af4f8?lang=en"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/winshining/nginx-http-flv-module/security/advisories/GHSA-8mc6-jrxv-29g9"},{"source":"security-advisories@github.com","tags":[],"url":"https://www.chtsecurity.com/news/b15d7b24-0a5e-4962-8b52-e4754e5af4f8?lang=en"}],"remediation":[],"revision":"978564e2f701a4a1e6112964f56c7260019ff311408a338da00cd6610e442365","sources":[{"modifiedAt":1794506103952,"name":"CNA: GitHub_M","retrievedAt":1794507106508,"url":"https://www.cve.org/CVERecord?id=CVE-2026-65982"},{"modifiedAt":1794431806903,"name":"NVD","retrievedAt":1794443548660,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-65982"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1794507135798,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-65982"}],"ssvc":{"assessedAt":1794501493537,"automatable":"yes","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"NULL-pointer dereference (DoS) in nginx-http-flv-module","updatedAt":1794507135798}
