Summary

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
