{"id":"CVE-2026-73034","summary":"DB-GPT v0.8.1 Path Traversal Arbitrary File Write via user_id Header","details":"DB-GPT v0.8.1 contains an unauthenticated path traversal vulnerability that allows remote attackers to write arbitrary files to any location on the server by injecting directory traversal sequences into the user_id HTTP header of the Python file-upload endpoint. Attackers can send a crafted multipart upload request with a traversal-poisoned user_id header to escape the intended upload directory and write attacker-controlled content to locations such as Python startup hooks, cron directories, or agent scripts, resulting in remote code execution.","modified":"2026-08-15T11:31:12.206615774Z","published":"2026-08-11T19:31:49.107Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73034.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-22"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73034.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-73034"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/db-gpt-path-traversal-arbitrary-file-write-via-user-id-header"},{"type":"REPORT","url":"https://github.com/eosphoros-ai/DB-GPT/issues/3104"},{"type":"FIX","url":"https://github.com/eosphoros-ai/DB-GPT/commit/e0c741bd2b5e521b128cffb3f68982dde3f7b359"},{"type":"PACKAGE","url":"https://github.com/eosphoros-ai/DB-GPT"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/eosphoros-ai/db-gpt","events":[{"introduced":"0"},{"fixed":"e0c741bd2b5e521b128cffb3f68982dde3f7b359"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"last_affected":"0.8.1"}]}}],"versions":["v0.8.1","v0.8.0","v0.7.5","v0.7.4","v0.7.3","v0.7.2","v0.7.1","v0.7.0","v0.6.3","v0.6.2","v0.6.1","v0.6.0","v0.5.10","v0.5.9","v0.5.8","v0.5.7","v0.5.6","v0.5.5","v0.5.4","v0.5.3","v0.5.2","v0.5.1","v0.5.0","v0.4.7","v0.4.6","v0.4.5","v0.4.4","v0.4.3","v0.4.2","0.4.1","v0.4.0","v0.3.9","v0.3.8","v0.3.7","v0.3.6","v0.3.5","v0.3.4","v0.3.3","v0.3.2","v0.3.1","v0.3.0","v0.2.3","v0.2.2","v0.2.1","v0.2.0","v0.1.1","v0.1.0","v0.0.7","v0.0.6","v0.0.5-beta","v0.0.4-alpha","v0.0.3","v0.0.2","v0.0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-73034.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
