Input passed via the "Discussion/Tags" parameter when creating or editing discussions is not properly sanitised before being used. 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. Successful exploitation requires the Tagging plugin to be enabled. The vulnerability is confirmed in version 2.0.18.4 running with Tagging plugin version 1.1p1. SOLUTION: Edit the source code to ensure that input is properly sanitised.
