CVE-2026-73812: Inconsistent Interpretation of HTTP Requests

httpd function checkheader/3 rejects duplicate Content-Length per CVE-2026-23941 but never checks for the TE+CL co-presence that RFC 9112 §6.3 identifies as a probable smuggling attempt. handlebody/3 frames by chunked and silently discards Content-Length. A CL-preferring front-end paired with...
