SCA: security update for kunstmaan/bundles-cms, kunstmaan/media-bundle (GHSA-p279-5wcv-45vq)

high Tenable Self-Hosted Container Security Plugin ID 473663

Description

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

 - Kunstmaan CMS is an open source content management system based on the Symfony framework. Prior to 7.3.2,
 src/Kunstmaan/MediaBundle/Helper/File/FileHandler.php performs the blacklisted_extensions check case-
 sensitively in FileHandler::getFilePath and lowercases the stored extension afterward. An authenticated
 backend user with media access can upload a mixed-case executable extension such as PHP that bypasses the
 check and is stored in the web-accessible media directory with an executable lowercase extension. The
 default blacklist also omits several server-executable extension types, allowing the same code-execution
 impact where the web server executes uploaded files. This issue is fixed in version 7.3.2.
 (CVE-2026-104890)

Solution

Update the kunstmaan/bundles-cms library and its related packages to version 7.3.2 or later.
