Shortcode deletion via missing CSRF nonce
Published Aug 16, 2023 · Updated Oct 8, 2024
CSRF in the Tiempo.com WordPress plugin 0 through 0.1.2 allows remote attackers to delete shortcodes through a forged request. The process_bulk_action() shortcode-management function accepts the delete action and shortcode identifier without validating a CSRF nonce. Exploitation requires a logged-in administrator to open an attacker-supplied URL; the resulting request deletes the chosen shortcode.
