Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Beszel versions before 0.18.7 have an insecure direct object reference in several hub API endpoints that take a system ID from the URL, including container logs and info, systemd info, and SMART refresh. Any authenticated user can reach these routes for any system if they know its ID, which bypasses the membership checks applied to the standard collection API. Upgrade to Beszel 0.18.7 or later.
