medium Tenable Cloud Security Plugin ID 445915

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, getEscapeFunction in
 src/internal/unix/dash.js fails to escape ~ after : or = when applications use the escape or escapeAll
 APIs on Unix with shell set to dash, or with shell set to true when Dash is the default, and interpolate
 the result into an assignment prefixed to a command. An attacker who controls the input can supply a value
 such as :~ to disclose the home-directory path and may change the location on which the command operates.
 This issue is fixed in versions 2.1.14 and 3.0.1. (CVE-2026-73411)

Solution

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