Pimcore is an Open Source Data & Experience Management Platform. A vulnerability identified as CVE-2026-23494 has been discovered in versions prior to 12.3.1 and 11.5.14, where the application fails to enforce proper server-side authorization checks on the API endpoint responsible for reading or listing static routes.
In Pimcore, static routes are custom URL patterns defined via the backend interface or the var/config/staticroutes.php file. These routes include regex-based patterns, controllers, variables, and priorities, and are registered automatically through the PimcoreStaticRoutesBundle within the MVC routing system.
Testing has revealed that an authenticated backend user lacking explicit permissions can invoke the API endpoint (e.g., GET /api/static-routes) and retrieve sensitive route configurations. This vulnerability poses a risk to organizations as it could lead to unauthorized access to sensitive information.
With a CVSS score of 4.3, this vulnerability is classified as medium severity, indicating a moderate level of risk. Organizations are urged to apply the necessary patches available in versions 12.3.1 and 11.5.14 to protect against potential exploitation.
Organizations should prioritize patching immediately to mitigate risks associated with this vulnerability.
Vulnerability Details
The vulnerability occurs due to a lack of server-side authorization checks on the API endpoint which manages static routes. This allows unauthorized users to access sensitive route configurations.
The vulnerability has a CVSS version of 3.1 and a vector string of CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N, with a base score of 4.3, indicating medium severity. The affected product is Pimcore, and the vulnerability was published on January 15, 2026.
Technical Analysis
The root cause of this vulnerability stems from improper authorization checks on the API endpoint that serves static routes. Attackers can exploit this flaw to gain access to sensitive route configurations, which could potentially lead to further security breaches.
The attack vector involves network access, and the complexity of the attack is low, requiring only low privileges and no user interaction. The confidentiality impact is classified as low, while integrity and availability impacts are negligible.
Risk & Impact Analysis
Organizations using affected versions of Pimcore may face significant risks due to the potential exposure of sensitive configuration data. The blast radius could extend to any user with backend access, leading to unauthorized modifications or information retrieval.
Given the CVSS score of 4.3, organizations should address this vulnerability in their priority patch cycle to mitigate potential risks effectively.

Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The affected versions include all versions prior to 12.3.1 and 11.5.14.
Mitigation & Remediation
Organizations should upgrade to Pimcore version 12.3.1 or 11.5.14 to remediate this vulnerability. If an immediate upgrade is not possible, consider implementing access controls to restrict unauthorized access to the API endpoints.
In addition, continuous monitoring of API access logs can help detect any unauthorized attempts to access sensitive configurations.
For further security assessments, organizations may consider engaging in penetration testing to reinforce their security posture.
Detection Guidance
To detect potential exploitation of this vulnerability, organizations should monitor logs for unusual API access patterns, particularly for the static routes endpoint.
Behavioral anomalies such as unexpected responses or access attempts from unauthorized users should also be investigated.
AppSecure Threat Intelligence Insight
The long-term significance of CVE-2026-23494 highlights the ongoing need for robust access controls in API design. This vulnerability represents a common oversight in web application security where authorization checks are not thoroughly enforced.
Security teams should take this incident as a lesson to implement comprehensive security reviews as part of their development lifecycle, ensuring that all endpoints are adequately protected against unauthorized access.
