SCA: security update for typicms/core (GHSA-xfvg-8v67-j7wp)

medium Tenable Cloud Security Plugin ID 437982

Description

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

 - TypiCMS is a multilingual content management system based on the Laravel framework. A Stored Cross-Site
 Scripting (XSS) vulnerability exists in the file upload module of TypiCMS prior to version 16.1.7. The
 application allows users with file upload permissions to upload SVG files. While there is a MIME type
 validation, the content of the SVG file is not sanitized. An attacker can upload a specially crafted SVG
 file containing malicious JavaScript code. When another user (such as an administrator) views or accesses
 this file through the application, the script executes in their browser, leading to a compromise of that
 user's session. The issue is exacerbated by a bug in the SVG parsing logic, which can cause a 500 error if
 the uploaded SVG does not contain a `viewBox` attribute. However, this does not mitigate the XSS
 vulnerability, as an attacker can easily include a valid `viewBox` attribute in their malicious payload.
 Version 16.1.7 of TypiCMS Core fixes the issue. (CVE-2026-27621)
