SCA: security update for github.com/dunglas/frankenphp (GHSA-g966-83w7-6w38)

critical Tenable Self-Hosted Container Security Plugin ID 437707

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - FrankenPHP is a modern application server for PHP. Prior to 1.11.2, 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 byte length of certain UTF-8 characters (e.g., Ⱥ expands
 when lowercased), the computed index may not align with the correct position in the original string. This
 results in an incorrect SCRIPT_NAME and SCRIPT_FILENAME, potentially causing FrankenPHP to execute a file
 other than the one intended by the URI. This vulnerability is fixed in 1.11.2. (CVE-2026-24895)

Solution

Update the github.com/dunglas/frankenphp library and its related packages to version 1.11.2 or later.
