QuickCMS is vulnerable to Cross-Site Scripting (XSS) through its insecure HTTP-based plugin‑fetching mechanism. A malicious attacker can perform a Man‑in‑the‑Middle (MITM) attack by impersonating the opensolution.org server and serving arbitrary HTML or JavaScript at the plugin list endpoint. When a user accesses the plugin page, the malicious content is automatically fetched, rendered, and executed. This issue was fixed in a patch to version 6.8 published on 15.05.2026, deployments without this patch are still vulnerable.

QuickCMS allows a user's session identifier to be set before authentication. The value of this session ID stays the same after authentication. This behaviour enables an attacker to fix a session ID for a victim and later hijack the authenticated session. This issue was fixed in a patch to version 6.8 published on 15.05.2026, deployments without this patch are still vulnerable.

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
