Summary
Slink before 1.12.3 fails to properly authorize access to image comment endpoints, allowing unauthenticated attackers to read comment threads via GET /api/image/{imageId}/comments and server-sent-events subscriptions. Attackers who obtain image IDs out of band can retrieve full comment threads on public images and subscribe to live comment updates without authentication or authorization checks.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
The maintainers of andrii-kryvoviaz/slink published their own advisory on GitHub. Reviewed sources take precedence over it.
