What to do now

Update CookieYes – Cookie Banner for Cookie Consent (Easy to setup GDPR/CCPA Compliant Cookie Notice) to 3.5.8 or later.

Affected versions

• Everything before 3.5.8

The CookieYes – Cookie Banner for Cookie Consent (Easy to setup GDPR/CCPA Compliant Cookie Notice) plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to 3.5.8. This is due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
