 "title": "Complianz GDPR/CCPA Cookie Consent Banner <= 7.5.5 - Unauthenticated Stored Cross-Site Scripting via YotuWP Cookie Blocker",
 "description": "The Complianz GDPR/CCPA Cookie Consent Banner plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the YotuWP integration's cookie blocker in all versions up to, and including, 7.5.5, due to a greedy regular expression and string replacements applied to the whole page output buffer. The rewrite inserts unescaped, double-quoted attribute markup wherever it finds the matched tokens, and the matched text can include visitor-supplied content such as comments. As a result, attribute values in that content can be broken out of. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page, on sites where the YotuWP plugin is active and YouTube is set up in Complianz.",
