What is CVE-2026-15550?

The Ninja Forms - Save Progress plugin for WordPress contains a Missing Authorization vulnerability allowing authenticated attackers, including those with subscriber-level access, to execute privileged actions. The vulnerability arises from inadequate capability checks and nonce verification in the 'bulk_actions' functionality. Consequently, this oversight enables unauthorized deletion of entries from the 'wp_nf3_objects' database table, leading to potential data loss of saved form submissions. Proper security measures should be adopted to secure against this risk.

Affected Version(s)

Ninja Forms - Save Progress 0 <= 3.0.30
