Ninja Forms - Save Progress - Broken Access Control (CVE-2026-15550)

CVE-2026-15550

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.

Exploitability Assessment

Exploitability is assessed as High based on remote code execution potential, low-bar exploit prerequisites.

Primary risk drivers: remote code execution potential, low-bar exploit prerequisites

Mitigation Recommendations

Validate affected product versions, prioritize patching, and monitor references for vendor remediation guidance. If immediate patching is not possible, apply compensating controls and limit exposure of vulnerable surfaces.

Detection & Monitoring

Track authentication anomalies, unexpected file writes, and suspicious plugin API activity around affected components.

What to do about this

Patch on your next cycle Worth fixing, but not ahead of other work.

Fix it

Update Ninja Forms - Save Progress to the latest available version.

Where the vendor has not published a fix yet, disable the plugin until they do.

Cannot update today? Request / payload inspection (WAF) in Hack Halt ProSecure blocks this class of attack before WordPress processes the request.

Inspect request parameters and bodies for injection, traversal and file-inclusion payloads, and refuse the request rather than logging it.
