Technical details
The vulnerability is a path traversal/arbitrary file write flaw in the `skill_upload` endpoint (packages/dbgpt-app/src/dbgpt_app/openapi/api_v1/agentic_data_api.py). The endpoint takes the multipart upload filename directly and constructs the destination path using path concatenation without canonicalization or validation. Filenames like `../../../tmp/x` or `/tmp/x` resolve outside the intended upload directory. The vulnerability is made critical by an authentication bypass: the endpoint's auth check (`get_user_from_headers`) grants admin privileges regardless of whether credentials are provided. An unauthenticated attacker can thus write arbitrary files—including malicious Python modules with .py suffixes into the application package—and achieve remote code execution when those modules are imported by the running application.
