GDPR Cookie Compliance cross-site request can clear user cookies
GDPR Cookie Compliance before 5.1.0 exposes a cookie-expiration action without authentication or request-origin validation. An attacker can lure a victim to a crafted link that invokes the action, deletes the site's cookies and logs the victim out. This unscored record received deeper review because the action is an unauthenticated service-disruption primitive that can affect any user. The CNA does not disclose the endpoint, action name or request parameters.

This CVE was published Aug 05, 2026 and is one of 10 known issues for this plugin.
Update, patch or deactivate.
Update GDPR Cookie Compliance to 5.1.0 or later. Unexpected logout events may have other causes, but review requests to the plugin's cookie-management actions if a vulnerable release was active.
A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.
Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
