Description
A stored XSS can be exploited by leveraging the usernames as an attack vector. When an admin user viewed the audit log details for affected entries, any malicious JavaScript payload embedded in the username would be executed due to missing output sanitisation. Proper escaping has been added to the audit log details output.
