{"id":"CVE-2026-27483","aliases":["GHSA-4894-xqv6-vrfq","PYSEC-2026-2205"],"url":"https://o3.security/vulnerability/CVE-2026-27483","summary":"MindsDB has Path Traversal in /api/files Leading to Remote Code Execution","details":"MindsDB is a platform for building artificial intelligence from enterprise data. Prior to version 25.9.1.1, there is a path traversal vulnerability in Mindsdb's /api/files interface, which an authenticated attacker can exploit to achieve remote command execution. The vulnerability exists in the \"Upload File\" module, which corresponds to the API endpoint /api/files. Since the multipart file upload does not perform security checks on the uploaded file path, an attacker can perform path traversal by using `../` sequences in the filename field. The file write operation occurs before calling clear_filename and save_file, meaning there is no filtering of filenames or file types, allowing arbitrary content to be written to any path on the server. Version 25.9.1.1 patches the issue.","published":"2026-02-24T14:00:05.402Z","modified":"2026-08-05T03:32:28.955469495Z","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":1,"affectedPackages":[{"ecosystem":"PyPI","name":"mindsdb","fixedVersion":"25.9.1.1"}],"fix":{"url":"https://github.com/mindsdb/mindsdb/commit/87a44bdb2b97f963e18f10a068e1a1e2690505ef","label":"mindsdb/mindsdb@87a44bd"},"references":[{"type":"WEB","url":"https://github.com/mindsdb/mindsdb/releases/tag/v25.9.1.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/27xxx/CVE-2026-27483.json"},{"type":"ADVISORY","url":"https://github.com/mindsdb/mindsdb/security/advisories/GHSA-4894-xqv6-vrfq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-27483"},{"type":"FIX","url":"https://github.com/mindsdb/mindsdb/commit/87a44bdb2b97f963e18f10a068e1a1e2690505ef"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-05T03:32:28.955469495Z"}}
