Prior to 2.5.1, YETI derives ExportTask.file_name from the user-controlled task name and passes it to core/clients/file_storage/classes/local_storage.py without sanitizing traversal sequences or enforcing path confinement. A low-privileged authenticated user using the default local storage backend can call POST /api/v2/tasks/export/new with a traversal name and use ExportTask.file_contents through GET /api/v2/tasks/export/{export_id}/content to read files accessible to the YETI service account. Running ExportTask.run() can also write attacker-controlled export output to an attacker-selected writable path. The impact depends on the service account's filesystem permissions, and universal code execution is not established. This issue is fixed in version 2.5.1.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":8.3,"severity":"high","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:L","version":"3.1"}],"modifiedAt":1793734566607,"publishedAt":1793734566607,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/yeti-platform/yeti/security/advisories/GHSA-4q3w-w2g5-8wqq"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/yeti-platform/yeti/pull/1280"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/yeti-platform/yeti/commit/bfd7c2424dc05dea2d46b5b106b5071f959d5d5a"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/yeti-platform/yeti/releases/tag/2.5.1"}],"remediation":[],"revision":"faa9f8a4646702ebd3ff1fc8e6d96c6e159c242b65819a4427712ad2b6eb8b28","sources":[{"modifiedAt":1793734566607,"name":"CNA: GitHub_M","retrievedAt":1793736608741,"url":"https://www.cve.org/CVERecord?id=CVE-2026-63502"}],"ssvc":null,"status":"published","title":"Yeti: Path traversal in ExportTask name allows authenticated arbitrary file read and write","updatedAt":1793736608741}
