critical Tenable Self-Hosted Container Security Plugin ID 438278

Description

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

 - Craft is a content management system (CMS). Prior to 4.17.0-beta.1 and 5.9.0-beta.1, an authenticated
 administrator can achieve Remote Code Execution (RCE) by injecting a Server-Side Template Injection (SSTI)
 payload into Twig template fields (e.g., Email Templates). By calling the craft.app.fs.write() method, an
 attacker can write a malicious PHP script to a web-accessible directory and subsequently access it via the
 browser to execute arbitrary system commands. This vulnerability is fixed in 4.17.0-beta.1 and
 5.9.0-beta.1. (CVE-2026-28697)
