Discussion

PunBB 'p' Parameter Multiple Cross-Site Scripting Vulnerabilities

An attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may allow the attacker to steal cookie-based authentication credentials and to launch other attacks.

Versions prior to PunBB 1.2.20 are vulnerable.
