CVE-2026-80104— DB-GPT 0.8.0 Path Traversal Arbitrary File Write via Skill Upload Filename

Quick assessment

Affected
eosphoros-ai DB-GPT
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

eosphoros DB-GPT是eosphoros组织开源的一款人工智能数据助手，可连接到数据，编写 SQL 和代码。 eosphoros DB-GPT 0.8.1之前版本存在路径遍历漏洞，该漏洞源于上传技能时未对multipart文件名进行路径限制，且相关接口缺少身份验证，可能导致远程攻击者无需凭据即可将恶意文件写入任意路径，从而实现远程代码执行。

Vulnerability Title
DB-GPT 0.8.0 Path Traversal Arbitrary File Write via Skill Upload Filename
Source: CVE Program / CVE List V5
Vulnerability Description
DB-GPT builds the destination path for an uploaded skill from the multipart filename without constraining it to the upload directory. skill_upload in packages/dbgpt-app/src/dbgpt_app/openapi/api_v1/agentic_data_api.py takes file.filename as given and writes the request body to upload_dir / filename. A path composed with that operator discards the left operand when the right one is absolute and follows parent references otherwise, so a filename such as ../../../tmp/x or /tmp/x resolves outside the intended directory; nothing canonicalises the result, checks that it remains under the upload root, or prevents a .py suffix. The route's only dependency is get_user_from_headers in dbgpt_serve/utils/auth.py, which returns a request carrying the admin role whether or not a user_id header is supplied, so the endpoint is reachable without credentials. A remote attacker holding no account can therefore write attacker-controlled bytes to any path the server process can write, place a new Python module inside the application package or replace one the application already imports, and obtain code execution in the server process when that module is next imported.
