PaNews is reportedly affected by a cross-site scripting vulnerability. This issue exists because the application fails to properly sanitize user-supplied input.

As a result of this vulnerability, it is possible for a remote attacker to create a malicious link containing script code that will be executed in the browser of an unsuspecting user when followed. This may facilitate the theft of cookie-based authentication credentials as well as other attacks.
