Detailsinfo

A vulnerability classified as critical has been found in DeepSeek-AI DeepInfer up to 0.1.0. Affected is an unknown functionality of the component Profile Endpoint. The manipulation of the argument output_dir with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

DeepInfer through 0.1.0 contains a path traversal vulnerability in the unauthenticated /profile endpoint that allows remote attackers to create arbitrary directories via the output_dir parameter. Attackers, including cross-site GET requests from an operator's browser, can write chrome trace files to exhaust disk or inodes and use error messages as a filesystem oracle.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-120204 since 10/31/2026. The exploitability is told to be easy. It is possible to launch the attack remotely.
