SCA: security update for sanitize-html (GHSA-vccv-cmxp-4j9h)

medium Tenable Self-Hosted Container Security Plugin ID 445538

Description

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

 - ApostropheCMS is an open-source Node.js content management system, and sanitize-html provides a simple
 HTML sanitizer with a clear API. Versions of sanitize-html prior to 2.17.5 use
 `allowedSchemesAppliedToAttributes` (default: `['href', 'src', 'cite']`) to gate the `naughtyHref()`
 function that blocks dangerous URI schemes like `javascript:` and `vbscript:`. The HTML specification
 defines 10+ attributes that accept URIs (`action`, `formaction`, `data`, `poster`, `background`, `ping`,
 `xlink:href`, `dynsrc`, `lowsrc`), but none of these are included in the default gate list. When a
 developer allows any of these attributes in their configuration, `javascript:` URIs pass through
 completely unmodified, enabling XSS. Version 2.17.5 patches the issue. (CVE-2026-53606)

Solution

Update the sanitize-html library and its related packages to version 2.17.5 or later.
