Chainguard: nemo: security update to 2.7.3-r39

high Tenable Self-Hosted Container Security Plugin ID 477162

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Black is the uncompromising Python code formatter. Prior to 26.10.1, the Black GitHub Action with
use_pyproject: true accepts tool.black.required-version from pyproject.toml without validating that it is
a released Black version specifier. An attacker who can submit a pull request can change that field to a
direct reference to attacker-controlled code, causing the workflow to install and execute the code in the
victim repository's GitHub Actions context. This issue is fixed in version 26.10.1. (CVE-2026-114134)

Solution

Update the nemo library and its related packages to version 2.7.3-r39 or later.
