Echo: sanitize-html: security update to 2.17.6

medium Tenable Cloud Security Plugin ID 461405

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. Prior to 2.17.6, sanitizeHtml() can
 pass disallowed executable markup through packages/sanitize-html/index.js when textarea or xmp is included
 in allowedTags because a literal solidus after the raw-text end-tag name is treated as text by htmlparser2
 and the ontext handler emits that content without escaping, while a browser parses the following img
 onerror markup as active HTML. This issue is fixed in version 2.17.6. (CVE-2026-63670)

Solution

Update the sanitize-html library and its related packages to version 2.17.6 or later.
