CVE-2025-15364Public exploitNetwork attack vector

Account takeover via unauthenticated CBC ciphertext modification

Published Jan 6, 2026 · Updated Jan 6, 2026

Privilege escalation in W3 Eden WordPress Download Manager 3.3.40 and earlier allows remote attackers to take over non-administrator accounts. Crypt.php encrypts the user object consumed by updatePassword with unauthenticated CBC encryption, allowing ciphertext modification before the method trusts the decrypted account identity. A reachable WordPress AJAX endpoint and a non-administrator target account are required; successful exploitation changes that account’s password and grants its existing privileges.
