The WP Posts Password Batch Manager WordPress plugin through 1.1 does not perform any capability or nonce check on a bulk post-password action that runs on an always-loaded admin handler, allowing unauthenticated attackers to reset or overwrite the password of every published post, disclosing password-protected content or locking all posts behind an attacker-chosen password.
