What is CVE-2026-73034?
CVE-2026-73034 is a critical path traversal vulnerability in eosphoros-ai DB-GPT, published on 11 Aug 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official 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.
Weakness: CWE-22
