Unauthenticated code execution via unvalidated include path
Published Jun 15, 2026 · Updated Jun 15, 2026
File inclusion in Brandfolder WordPress Plugin 3.0 and earlier allows remote attackers to read server files or execute PHP code. The directly reachable callback.php concatenates the unvalidated wp_abspath request value with fixed WordPress filenames and passes each result to require_once. No authentication is required; local file disclosure uses a traversed path, while remote code execution depends on PHP accepting URL includes and an attacker-controlled remote file.
