Doc Text:
A flaw was found in Grafana. The application fails to verify creation permissions on destination folders during panel update operations. An authenticated user with edit permissions in one folder can exploit this vulnerability through the library elements API to move a library panel into a folder where they only possess view permissions. This allows an unauthorized user to bypass access controls and place content into restricted folders.

Description OSIDB Bzimport 2026-09-29 21:07:06 UTC
An authenticated user with edit permission on one folder can move a library panel into another folder where they only have view permission, through the library elements API or the equivalent App Platform resource. The update path did not check library panel create permission on the destination folder (incorrect authorization). No data from the destination folder is disclosed, and existing content there cannot be changed.
