SCA: security update for apostrophe (GHSA-vmgj-9cwm-cf3h)

medium Tenable Cloud Security Plugin ID 476556

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 4.34.0, the color field
 accepts trailing content after a valid rgb() or hsl() prefix because its TinyColor validation does not
 require the entire value to match a color. An authenticated user with edit rights can store arbitrary HTML
 after a valid color prefix. When the stored value is rendered, the payload executes, resulting in stored
 XSS. This issue is fixed in version 4.34.0. (CVE-2026-112951)

Solution

Update the apostrophe library and its related packages to version 4.34.0 or later.
