DSGVO All in one for WP <= 5.0 - Unauthenticated Stored Cross-Site Scripting via Comment Content via Output Buffer Regex Corruption

The DSGVO All in one for WP plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Content via Output Buffer Regex Corruption in all versions up to, and including, 5.0 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. This is only exploitable when the administrator has enabled both the 'Google Tag Manager' integration and the 'Replace integration automatically [Beta]' option, and requires the crafted comment to be approved by an administrator.
