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.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":7.1,"severity":"high","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L","version":"3.1"}],"modifiedAt":1793734621798,"publishedAt":1793734621798,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/yeti-platform/yeti/security/advisories/GHSA-6xf2-8436-rgvf"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/yeti-platform/yeti/pull/1279"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/yeti-platform/yeti/commit/8e36bd0000f98f625540e37eeb9f304c684e8394"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/yeti-platform/yeti/releases/tag/2.5.1"}],"remediation":[],"revision":"69a2353892abd518cedb00509aff63cb68995bd592907391bb73efc49fcf370a","sources":[{"modifiedAt":1793734621798,"name":"CNA: GitHub_M","retrievedAt":1793736605969,"url":"https://www.cve.org/CVERecord?id=CVE-2026-63500"}],"ssvc":null,"status":"published","title":"Yeti: Path traversal in DFIQ uuid allows authenticated arbitrary file write during archive export","updatedAt":1793736605969}
