DescriptionCVE.org

The Ninja Forms - Save Progress plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 3.0.30. This is due to the lack of capability checks and nonce verification in the 'bulk_actions' function. This makes it possible for authenticated attackers, with subscriber-level access and above, to delete arbitrary database records from the 'wp_nf3_objects' table, such as saved submissions.

AnalysisAI

Missing authorization in the Ninja Forms - Save Progress WordPress plugin (versions ≤3.0.30) allows any subscriber-level authenticated user to bulk-delete arbitrary records from the wp_nf3_objects database table via the unprotected bulk_actions function. The handler enforces neither WordPress capability checks nor nonce verification, meaning any logged-in site user can destroy saved form submission data at will. …
