QuickCMS is vulnerable to Cross-Site Request Forgery across multiple endpoints. An attacker can craft special website, which when visited by the victim, will automatically send a POST request with victim's privileges. This software does not implement any protection against this type of attack. All forms available in this software are potentially vulnerable. This issue was fixed in a patch to version 6.8 published on 14.05.2026, deployments without this patch are still vulnerable
