Incorrect Behavior Order: Validate Before Canonicalize
Overview Affected versions of this package are vulnerable to Incorrect Behavior Order: Validate Before Canonicalize via the splitPos function. An attacker can cause unintended execution of files by crafting URLs with specific Unicode characters that manipulate the path splitting logic, potentiall...
GHSA-5R3V-VC8M-M96G Caddy: Unicode case-folding length expansion causes incorrect split_path index in FastCGI transport
Summary 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 strings.ToLower can change UTF-8 byte length for some characters. As a result, Caddy can deri...

CVE-2026-27590
Caddy prior to 2.11.1 is affected. The FastCGI path-splitting logic lowercased the request path to compute a split index, then used that index on the original path; Unicode can change byte length after lowercasing, causing SCRIPT_NAME/SCRIPT_FILENAME and PATH_INFO misalignment. This path confusio...
