{"id":"CVE-2026-63500","published":"2026-11-03T20:18:16.910","lastModified":"2026-11-03T23:17:51.443","description":"Yeti bridges the gap between CTI and DFIR practitioners by providing a Forensics Intelligence platform and pipeline. Prior to 2.5.1, core/schemas/dfiq.py accepts an unvalidated uuid from DFIQ YAML through POST /api/v2/dfiq/from_yaml, and core/web/apiv2/dfiq.py later interpolates that stored value into an archive filesystem path in POST /api/v2/dfiq/to_archive. A low-privileged authenticated user can import a DFIQ object whose UUID contains traversal sequences and trigger archive export, causing attacker-controlled content with a .yaml suffix to be written outside the intended temporary archive directory. The impact is limited by paths writable by the YETI service account, and the separate DFIQ archive-import zip-slip candidate is not part of this vulnerability. This issue is fixed in version 2.5.1.","cvssScore":7.1,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L","cwes":["CWE-22"],"vendors":[],"products":[],"references":[{"url":"https://github.com/yeti-platform/yeti/commit/8e36bd0000f98f625540e37eeb9f304c684e8394","tags":[]},{"url":"https://github.com/yeti-platform/yeti/pull/1279","tags":[]},{"url":"https://github.com/yeti-platform/yeti/releases/tag/2.5.1","tags":[]},{"url":"https://github.com/yeti-platform/yeti/security/advisories/GHSA-6xf2-8436-rgvf","tags":[]}],"exploitRefs":[{"url":"https://github.com/yeti-platform/yeti/commit/8e36bd0000f98f625540e37eeb9f304c684e8394","tags":[]},{"url":"https://github.com/yeti-platform/yeti/pull/1279","tags":[]},{"url":"https://github.com/yeti-platform/yeti/releases/tag/2.5.1","tags":[]},{"url":"https://github.com/yeti-platform/yeti/security/advisories/GHSA-6xf2-8436-rgvf","tags":[]}],"hasPoc":true,"ai":null}
