Stored Cross-Site Scripting (XSS) vulnerability in the CoverManager booking software. This allows an attacker to inject malicious scripts into the application, which are permanently stored on the server. The malicious scripts are executed in the browser of any user visiting the affected page without the user having to take any further action. This can allow the attacker to steal sensitive information, such as session cookies, login credentials, and perform actions on behalf of the affected user.
