The GDPR Cookie Compliance WordPress plugin before 4.15.7 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfilteredhtml capability is disallowed (for example in multisite setup).

The WP Cookie Consent ( for GDPR, CCPA & ePrivacy ) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘Client-IP’ header in all versions up to, and including, 3.2.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The WP Cookie Consent ( for GDPR, CCPA & ePrivacy ) plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the gdprpolicyprocessdelete() function in all versions up to, and including, 3.0.2. This makes it possible for unauthenticated attackers to delete arbitrary posts.
