CVE-2026-65161 · Severity: high · CVSS 7.5 · Published 2026-10-13

NVIDIA AIStore for Linux, a distributed storage framework, contains an unauthenticated path traversal vulnerability in its Promote API. An attacker without credentials can read arbitrary files accessible to the AIStore process by crafting malicious requests with absolute paths, leading to sensitive data exposure.

Technologies: [Nvidia AIStore](https://junglewise.ai/threats/technologies/aistore). Vendors: [Nvidia](https://junglewise.ai/threats/vendors/nvidia).

**How is CVE-2026-65161 attacked?** It is attacked over the network, in a software library.

**Am I affected by CVE-2026-65161?** Check whether you run Nvidia AIStore. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

## Technical details

The Promote API fails to validate or sanitize absolute source paths supplied by unauthenticated users, allowing path traversal attacks. An attacker can exploit this via network requests to read files in the filesystem namespace of the target process. The vulnerability requires no authentication, user interaction, or special privileges beyond network access to the API endpoint.
