Vulnerability Title
DB-GPT v0.8.1 Path Traversal Arbitrary File Write via user_id Header
Source: CVE Program / CVE List V5
Vulnerability Description
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.

# POC Description Source Link Shenlong Link
1 DB-GPT through 0.8.1 allows unauthenticated arbitrary file writes via a path traversal in the user_id HTTP header of the POST /api/v1/python/file/upload endpoint, letting attackers escape the intended upload directory and write files anywhere, as confirmed by the reflected upload path in the JSON response. https://github.com/projectdiscovery/nuclei-templates/blob/main/http/cves/2026/CVE-2026-73034.yaml POC Details
