CVE-2026-6626 Details
Description
A vulnerability was detected in Cockpit-HQ Cockpit up to 2.13.5. Affected by this issue is some unknown functionality of the component Asset Handler/Aggregate Handler. The manipulation results in improper neutralization of special elements in data query logic. It is possible to launch the attack remotely. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
A critical NoSQL injection vulnerability has been identified in Cockpit-HQ Cockpit CMS versions through 2.13.5. This vulnerability arises from improper sanitization of user-controlled JSON objects in data query logic, allowing authenticated attackers to exploit MongoDB operators for data exfiltration. The issue is present in the Asset Handler and Aggregate Handler components, specifically within the 'POST /assets/assets' and '/api/content/aggregate/{model}' endpoints. Exploitation can lead to unauthorized access to sensitive data, including administrative credentials and personal information.
It is recommended to implement a recursive sanitizer that removes all keys starting with '$' from user-provided objects before they are sent to the database. Additionally, the aggregation API should be restricted to allow only certain stages, blocking operators like '$lookup' and '$unionWith' for non-superadmin users.
