CVE-2024-6554Network attack vector

Full-path disclosure via directly accessible Composer helper

Published Jul 11, 2024 · Updated Apr 8, 2026

Full-path disclosure in WPMU DEV Branda 3.4.18 and earlier allows remote attackers to read the WordPress installation path. The misc/composer/prefix-fixer.php Composer helper permits direct web requests and emits a PHP error containing the server-side path. No authentication or user interaction is required, but the path is only useful when combined with another vulnerability.
