What fixes it
- 0.77.3VelociraptorCVE List
A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.
Description
Velociraptor's SetClientMetadata used the wrong permission check to enforce setting metadata on the server. This allows a user with LABEL_CLIENTS permission to update the server metadata.
Server metadata is often used to store site wide configuration data that should only be updated by the server admin.
