CVE-2026-63379: Libevent Http Trailer Header Injection
HTTP chunked trailers are parsed directly into request headers via `evhttp_parse_headers_`, which can cause trailer headers to merge into request headers and allow HTTP request smuggling or header spoofing. Trailers should be parsed into a separate temporary list and discarded.
