Arbitrary log deletion via nonce-free AJAX action
Published Jan 16, 2024 · Updated Jun 2, 2025
Cross-site request forgery in WPExperts Post SMTP before 2.5.7 allows remote attackers to delete arbitrary email logs via AJAX. The ps-delete-email-logs action accepts attacker-chosen selected[] log identifiers and performs deletion without validating a CSRF nonce. A logged-in user with manage_postman_smtp capability must open an attacker-controlled page, causing selected log records or all logs to be removed.
