iubenda < 3.13.7 - Unauthenticated Stored XSS via Cookie Block HTML Parser
What happened?
The iubenda | All-in-one Compliance for GDPR / CCPA Cookie Consent + more WordPress plugin before 3.13.7 does not properly escape content it re-emits through its bundled HTML parser, allowing unauthenticated users to inject arbitrary web scripts in pages that will execute in the session of any visitor viewing them, including logged in administrators.
