Attack profile from CVSS 3.1 · CNA. Fix status from CNA. Impact type from CWE-306.
Summary
Yeti before 2.5.1 registers its audit router without an authentication requirement, so the /api/v2/audit/timeline/{id} endpoint does not check for a logged-in user (CWE-306). An unauthenticated network attacker can query timeline records that include analyst usernames, object identifiers and values, and before-and-after object data. The flaw exposes the operational history of threat intelligence objects.

Description from the CNA
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.
