CVE-2026-27590 Caddy: Unicode case-folding length expansion causes incorrect split_path index (SCRIPT_NAME/PATH_INFO confusion) in FastCGI transport

Caddy is an extensible server platform that uses TLS by default. Prior to version 2.11.1, Caddy's FastCGI path splitting logic computes the split index on a lowercased copy of the request path and then uses that byte index to slice the original path. This is unsafe for Unicode because...

GHSA-G966-83W7-6W38 FrankenPHP's unicode case-folding length expansion causes incorrect split_path index (SCRIPT_NAME/PATH_INFO confusion) in FrankenPHP

Summary FrankenPHP’s CGI path splitting logic improperly handles Unicode characters during case conversion. The logic computes the split index for finding .php on a lowercased copy of the request path but applies that byte index to the original path. Because strings.ToLower in Go can increase the...
