GHSA-G7PC-PC7G-H8JH Caddy: MatchPath %xx (escaped-path) branch skips case normalization, enabling path-based route/auth bypass

Summary Caddy's HTTP path request matcher is intended to be case-insensitive, but when the match pattern contains percent-escape sequences %xx it compares against the request's escaped path without lowercasing. An attacker can bypass path-based routing and any access controls attached to that rou...

CVE-2026-27588

Summary (CVE-2026-27588) Caddy (v2.x) vulnerability in the host matcher: when a large allowlist (>100 hosts) is configured, the MatchHost algorithm uses a fast path that enforces a case-sensitive comparison, which makes the host matching effectively case-sensitive and can bypass host-based rou...
