What is CVE-2026-16613?

The GDPR Cookie Compliance plugin for WordPress, prior to version 5.1.0, contains an authentication bypass vulnerability that allows an attacker to exploit cookie expiration functionality. Due to a lack of authentication checks, an unauthorized user can craft a link to log out any visitor and remove the associated cookies. This can lead to session hijacking or loss of user cookies, potentially compromising the website's security.

Affected Version(s)

GDPR Cookie Compliance 0 < 5.1.0
