Summary

The Jenkins VncRecorder Plugin versions up to and including 1.25 is susceptible to a reflected cross-site scripting (XSS) vulnerability. This flaw occurs due to improper escaping of a parameter value in the form validation endpoint 'checkVncServ', allowing adversaries to inject malicious scripts that execute in the context of the user's browser. This can lead to unauthorized actions and data exposure. Users are urged to upgrade to the latest version to mitigate potential risks.
