Which packages are affected by GHSA-rpx7-33j2-xx9x?

GHSA-rpx7-33j2-xx9x affects the following packages: nemo-toolkit (PyPI). Ecosystems affected: PyPI.

How do I fix GHSA-rpx7-33j2-xx9x?

Update nemo-toolkit to 1.6.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rpx7-33j2-xx9x is resolved across your whole dependency graph.

How do I detect GHSA-rpx7-33j2-xx9x in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for nemo-toolkit, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-rpx7-33j2-xx9x if there is no patch (or I can't update yet)?

Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.

Is GHSA-rpx7-33j2-xx9x actively exploited in the wild?

Description

NVIDIA NeMo contains a vulnerability in ASR WebApp, where Relative Path Traversal (CWE-23) may lead to deletion of any directory through the "../" structure when admin privileges are available.

CVSS Score = 2.0 https://nvd.nist.gov/vuln-metrics/cvss/v3-calculator?vector=AV:L/AC:L/PR:H/UI:R/S:U/C:N/I:L/A:N

Impact

When the optional tool ASR Webapp (https://github.com/NVIDIA/NeMo/tree/main/tools/asr_webapp) is used prior to commit https://github.com/NVIDIA/NeMo/commit/f7e4ed7e4f7f2fa43765a38c2fafa1b6d1ebd7c0, some interfaces do not verify user input. Malicious attackers can construct malicious requests to delete any directory through the "../" structure.

The vulnerability affects only cases where this particular web app is started by a user with superuser permissions. The web application is not a part of the regular pip release or the corresponding container, and impacts only users that clone the repository in its entirety and execute the web app (while also possessing superuser permissions).

Patches

This vulnerability has been patched via https://github.com/NVIDIA/NeMo/commit/f7e4ed7e4f7f2fa43765a38c2fafa1b6d1ebd7c0, which is effectively any clone of the repository post r1.5.1 branch. Since the web app is not distributed via pip release or container, users who clone the main branch post this commit will possess the patch.

Workarounds

The changes in commit https://github.com/NVIDIA/NeMo/commit/f7e4ed7e4f7f2fa43765a38c2fafa1b6d1ebd7c0 can be applied to any version of the web app without any adverse effect.
