Published Nov 11, 2026 CVSS 4.0 · 8.7 High EPSS < 1% KEV · Not listed
Description
nginx-http-flv-module is a media streaming server based on nginx-rtmp-module. 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.
