Summary

Yeti bridges the gap between CTI and DFIR practitioners by providing a Forensics Intelligence platform and pipeline. Prior to 2.5.1, YETI registers the audit router without Depends(auth.get_current_active_user), and core/web/apiv2/audit.py does not perform a route-level authentication check for /api/v2/audit/timeline/{id}. An unauthenticated network attacker can use an empty, partial, or specific wildcard path to query TimelineLog records containing the actor, target_id, action, and details fields, including analyst usernames, object identifiers and values, and before-and-after object data. This exposes the operational history of threat-intelligence objects while other application routers require authentication. This issue is fixed in version 2.5.1.

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 yeti-platform/yeti published their own advisory on GitHub. Reviewed sources take precedence over it.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
