SCA: security update for shescape (GHSA-w4hw-qcx7-56pr)

critical Tenable Self-Hosted Container Security Plugin ID 445916

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/win/cmd.js does not escape `(` and `)` when applications use the escape or escapeAll APIs on
 Windows with shell set to cmd.exe, or with shell set to true when CMD is the default. An attacker-
 controlled argument can break out of a parenthesized CMD construct and inject shell syntax depending on
 the original command, resulting in arbitrary command execution. This issue is fixed in versions 2.1.14 and
 3.0.1. (CVE-2026-73414)

Solution

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