CVE-2026-78411

This allows a user with LABEL_CLIENTS permission to update the server metadata.

MEDIUM 6.5EPSS 0.18%

Does this matter?

Lower severity and a low EPSS score (0.18%). Track it; it rarely justifies an emergency change on its own.

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.
