CVE-2026-63500: Yeti path traversal in DFIQ UUID archive export

CVE-2026-63500 · Severity: high · CVSS 7.1 · Published 2026-11-03

Yeti is a forensics intelligence platform used by threat intelligence and digital forensics teams. A flaw in how Yeti validates UUID fields in DFIQ (Digital Forensics and Incident Response Questions) allows an authenticated user to inject path traversal sequences that, when combined with the archive export function, write arbitrary YAML files outside the intended directory on the server. An attacker with low-level access could write malicious files in unexpected locations, potentially leading to code execution or data integrity compromise depending on the writable paths available to the Yeti service account.

How to fix

  • Fixed in: 2.5.1

Technical details

The vulnerability is a path traversal (CWE-22) affecting DFIQ object handling. An authenticated attacker can import a DFIQ object with a malicious UUID containing traversal sequences (e.g., "../../../../tmp/pwn") via POST /api/v2/dfiq/from_yaml, then trigger archive export via POST /api/v2/dfiq/to_archive, which unsafely interpolates the UUID into a filesystem path. The fix validates UUIDs against RFC 4122 format at import time and adds path confinement checks at export time using path resolution verification.

Affected products
