Description

In SiCKRAGE, versions 9.3.54.dev1 to 10.0.11.dev1 are vulnerable to Reflected Cross-Site-Scripting (XSS) due to user input not being validated properly in the `quicksearch` feature. Therefore, an attacker can steal a user's sessionID to masquerade as a victim user, to carry out any actions in the context of the user.

Affected products

sickrage: from 9.3.54 before 10.0.11; 10.0.11-dev1 — fixed in 10.0.11

How to fix

Upgrade to a fixed version: sickrage 10.0.11. Check the vendor advisory for mitigations.
