SCA: security update for shescape (GHSA-6v4m-fw66-8r4x)

medium Tenable Self-Hosted Container Security Plugin ID 445917

Description

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

- Shescape is a simple shell escape library for JavaScript. Prior to 2.1.14 and 3.0.1, this impacts users of
Shescape on Unix systems that explicitly configure shell to Zsh, or true when the default shell is Zsh,
using the escape and escapeAll. The Zsh options EXTENDED_GLOB and MAGIC_EQUAL_SUBST exacerbate the
problem. In certain case, an attacker can leverage home directory expansion and extended glob syntax to
obtain lists of files and directories on the system. Depending on what the command does, this may be used
to leak more information. This issue is fixed in versions 2.1.14 and 3.0.1. (CVE-2026-73412)

Solution

Update the shescape library and its related packages to version 2.1.14 or later.
