Name of the Vulnerable Software and Affected Versions: snapd versions 2.27 through 2.29.2

Description: The issue allows unprivileged, unauthenticated users to bypass systemd-journald's access restrictions by making the 'snap logs' command call journalctl without match arguments.

Recommendations: For snapd versions 2.27 through 2.29.2, consider restricting access to the snap logs command until a patch is available. As a temporary workaround, avoid using the snap logs command with unprivileged or unauthenticated users to minimize the risk of exploitation.
