# CVE-2026-63482: Yeti: Unauthenticated Access to Full Audit Timeline Discloses All Threat Intelligence Data

Status: published. Published: 2026-11-03. Updated: 2026-11-03.

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.
