## Technical details

The vulnerability is a stored XSS flaw in the display_name parameter within the plugin's GDPR/Consent logging functionality, affecting versions up to 4.1.0. Exploitation requires an authenticated attacker with subscriber-level access and a Legal Consent record on file; when triggered, injected scripts execute in the context of any user viewing the Consent Logs column in wp-admin/users.php. The plugin insufficiently sanitizes input and fails to escape output, allowing persistence of malicious payloads.
