TIMELINE Jul 22 Reserved by VulnCheck Jul 24 Published (CNA: VulnCheck) Jul 25 EXPLOIT PUBLISHED — CVE-2026-65693 (microweber). Public exploit reference added.
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.
