GHSA-3G8V-8R37-CGJM FrankenPHP: Unsafe Unicode Handling in CGI Path Splitting Allows Execution of Non-PHP Files

Summary The splitPos function in cgi.go misuses golang.org/x/text/search with search.IgnoreCase when the request path contains a non-ASCII byte. Two distinct flaws in that fallback let an attacker mislead FrankenPHP into treating a non-.php file as a .php script. In any deployment where the...

Improper Handling of Case Sensitivity

Overview Affected versions of this package are vulnerable to Improper Handling of Case Sensitivity through improper handling of Unicode characters in the splitPos function. An attacker can execute arbitrary code by uploading a file with a specially crafted name containing non-ASCII bytes or Unico...

CVE-2026-24895

FrankenPHP CGI path splitting bug before 1.11.2 uses lowercased path for split index and applies it to the original path, causing SCRIPT_NAME/SCRIPT_FILENAME to point to the wrong file and potentially execute an unintended file. Root cause: Go strings.ToLower can increase byte length for certain ...
