GHSA-G754-HX8W-X2G6 quic-go HTTP/3 QPACK Header Expansion DoS

Summary An attacker can cause excessive memory allocation in quic-go's HTTP/3 client and server implementations by sending a QPACK-encoded HEADERS frame that decodes into a large header field section many unique header names and/or large values. The implementation builds an http.Header used on th...

CVE-2025-14523

A flaw in libsoup’s HTTP header handling allows multiple Host: headers in a request and returns the last occurrence for server-side processing. Common front proxies often honor the first Host: header, so this mismatch can cause vhost confusion where a proxy routes a request to one backend but the...
