CVE-2025-54387: IPX Allows Path Traversal via Prefix Matching Bypass
(updated )
The approach used to check whether a path is within allowed directories is vulnerable to path prefix bypass when the allowed directories do not end with a path separator. This occurs because the check relies on a raw string prefix comparison.
