web@all is prone to a cross-site scripting vulnerability and a cross-site request-forgery vulnerability.

An attacker can exploit these vulnerabilities to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site, steal cookie-based authentication credentials, add, delete or modify sensitive information, or perform unauthorized actions. Other attacks are also possible.
