Quick.Cart is vulnerable to Cross-Site Request Forgery in admin config panel. Malicious attacker can craft special website, which when visited by the admin, will automatically send a POST request that changes admin's login and password.
This software does implement simple protection against this type of attack, but it is easily bypassed by manipulating the referer header. All forms available in this software are potentially vulnerable.
This issue was fixed in a patch to version 6.7 published on 09.11.2026, deployments without this patch are still vulnerable
CVE-2026-33385 is a Blind SQL Injection vulnerability in OpenSolution Quick.CMS version 6.8. It arises from improper neutralization of input fields in the administration panel, which is accessible to high-privileged users. The vulnerability allows bypassing front-end validation and could lead to database manipulation or destruction. The vendor has not provided a patch or remediation, citing the trust model of the administration panel and its existing modification capabilities. No known exploits are reported in the wild.
Quick.Cart stores hard-coded, plaintext admin credentials in a configuration file. This flaw allows attackers with access to the server file system to retrieve authentication details, potentially leading to privilege escalation.
The vendor assessed the likelihood of exploitation as very low and determined that a fix is not necessary.
Only version 6.7 was tested but all versions should be considered as vulnerable.
A Path Traversal vulnerability exists in Quick.CMS through the URI path component of HTTP requests, where the server fails to normalize dot-dot-slash (../) sequences before resolving and serving the requested file. An authenticated attacker with admin privileges can use this vulnerability to read contents of files located in the sibling directory of the webroot via a crafted HTTP request containing ../ sequences in the URI.
The vendor assessed the likelihood of exploitation as very low and determined that a fix is not necessary.
Quick.CMS is vulnerable to Local File Inclusion (LFI) in the admin.php endpoint via the p parameter. An authenticated attacker with admin privileges can include arbitrary files located within the application's directory structure via a crafted HTTP request. Successful exploitation allows disclosure of the server's directory structure and absolute file paths (path disclosure).
The vendor assessed the likelihood of exploitation as very low and determined that a fix is not necessary.
In Quick.CMS, the administrative user interface restricts deletion of the primary language by omitting the corresponding option from the interface; however, the underlying language-deletion API endpoint does not enforce an equivalent server-side authorization check. As a result, an authenticated administrator can bypass the UI-level restriction and delete the primary language by sending a direct HTTP request to the API endpoint. Successful deletion of the primary language results in a Denial of Service (DoS) of application.
Critically, when combined with a separate Cross-Site Request Forgery (CSRF) vulnerability (CVE-2026-1468) an unauthenticated remote attacker can craft a malicious link, which if visited by an authenticated administrator, will trigger the DoS condition without direct access to the application
The vendor assessed the likelihood of exploitation as very low and determined that a fix is not necessary.
Quick.CMS deserializes user-controlled data received over plaintext HTTP without ensuring integrity or authenticity. This allows attackers to tamper with serialized payloads in transit and inject malicious objects. Because deserialization is performed without proper validation or class restrictions, crafted payloads can trigger dangerous magic methods (e.g., __wakeup() and __destruct()) and leverage gadget chains, resulting in arbitrary code execution. Exploitation is triggered automatically when an administrator accesses the admin panel.
When successfully exploited, this vulnerability allows attackers to execute arbitrary code on the server via manipulated serialized data transmitted over an unprotected channel.
This issue was mitigated by limiting the communication to HTTPS in a patch for version 6.8 published on 14.05.2026, deployments without this patch remain vulnerable.
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.

The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only version 6.7 was tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.
In Quick.Cart user passwords are stored in plaintext form. An attacker with high privileges can display users' password in user editing page.
The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only version 6.7 was tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.
Quick.Cart is vulnerable to Local File Inclusion and Path Traversal issues in the theme selection mechanism. Quick.Cart allows a privileged user to upload arbitrary file contents while only validating the filename extension. This allows an attacker to include and execute uploaded PHP code, resulting in Remote Code Execution on the server.
