CVE-2026-66724: CWE-862: Missing Authorization in CERT.PL MWDB Core
MWDB Core versions >=2.0.0 and <2.19.0 contain a missing authorization vulnerability in the deprecated config and blob upload endpoints. These endpoints accept the undocumented POST method, which bypasses the capability checks applied to the documented PUT method. This allows any authenticated user without the adding_configs or adding_blobs capabilities to upload config and text blob objects to the system. The impact is limited to adding new config and blob objects. This issue has been fixed in version 2.19.0

Technical Summary
CVE-2026-66724 describes a missing authorization vulnerability (CWE-862) in CERT.PL's MWDB Core product. Versions >=2.0.0 and <2.19.0 have deprecated config and blob upload endpoints that accept an undocumented POST method. This POST method bypasses capability checks that are enforced on the documented PUT method, enabling any authenticated user lacking the adding_configs or adding_blobs capabilities to upload configuration and text blob objects. The vulnerability is limited to unauthorized addition of these objects and does not affect other capabilities. The issue has been resolved in MWDB Core version 2.19.0.
Potential Impact
An authenticated user without the required capabilities can upload new config and blob objects due to missing authorization checks on an undocumented POST method. This could lead to unauthorized data insertion but does not allow modification or deletion of existing data or escalation beyond adding these objects. The impact is therefore limited in scope.
Mitigation Recommendations
This vulnerability is fixed in MWDB Core version 2.19.0. Users should upgrade to version 2.19.0 or later to remediate this issue. Patch status is not explicitly stated beyond the fix in 2.19.0, so verifying the upgrade with the vendor advisory is recommended.
