Vanilla Forums LatestComment Plugin Discussion Title Script Insertion Vulnerability


Description   Henry Hoggard has discovered a vulnerability in the LatestComment plugin for Vanilla Forums, which can be exploited by malicious users to conduct script insertion attacks.
Input passed via a discussion title is not properly sanitised before being used within the "Latest Commented" display. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site if malicious data is viewed.
The vulnerability is confirmed in version 1.1. Other versions may also be affected.
