No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

Microweber CMS through 2.0.20 contains a server-side template injection vulnerability that allows authenticated administrators to achieve arbitrary OS command execution by injecting Twig expressions into mail templates. Attackers can exploit the unsandboxed Twig environment in TwigView::render(), which lacks SandboxExtension or a SecurityPolicy, to inject malicious expressions such as filter('system') into mail template bodies stored unsanitized in the database, causing automatic payload execution on each subsequent application event that triggers a mail dispatch.
