We have identified and fixed a cross-site scripting (XSS) vulnerability in the Crucible comments search.

Affected versions are Crucible 2.2.6 to 2.5.0 inclusive.

XSS vulnerabilities potentially allow an attacker to embed their own JavaScript into a FishEye/Crucible page. You can read more about XSS attacks at various places on the web, including these:
