Gdpr Cookie Consent - Cross-Site Request Forgery (CSRF) (CVE-2026-15136)

Q: Am I affected by this vulnerability?

You are affected if your site runs Gdpr Cookie Consent. No account is needed to exploit this, so a public site is reachable by anyone.

Q: How do I fix it?

Update Gdpr Cookie Consent to the latest available version. Where the vendor has not yet published a fix, remove or disable the plugin until they do. Until you can update, Request / payload inspection (WAF) in Hack Halt ProSecure contains this class of attack at the request layer.

Q: What can an attacker actually do?

This is a Cross-Site Request Forgery (CSRF) flaw. An attacker who exploits it can make a logged-in administrator perform an action just by visiting a page.

CVE-2026-15136

Vulnerability CVE-2026-15136 PLUGIN gdpr-cookie-consent MEDIUM

The Cookie Banner for GDPR / CCPA – WPLP Cookie Consent plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 4.3.7. This is due to missing or incorrect nonce validation on the process_bulk_action function. This makes it possible for unauthenticated attackers to permanently delete or forcibly resolve arbitrary GDPR data request records stored in the wpl_data_req table via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

What to do about this

Patch promptly The consequence is significant even where an attacker needs a foothold first.

Fix it

Update Gdpr Cookie Consent 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.
