AnalysisAIv1 – Mar 12, 2026

Remote code execution in Statmatic CMS versions prior to 5.73.11 and 6.4.0 allows authenticated users with control panel access and permission to modify Antlers-enabled fields to execute arbitrary code in the application context. An attacker exploiting this vulnerability can fully compromise the application, including stealing sensitive configuration data, modifying or exfiltrating user data, and disrupting availability. A patch is available and exploitation requires authenticated access with specific field configuration permissions.

DescriptionGitHub Advisory

Statmatic is a Laravel and Git powered content management system (CMS). Prior to versions 5.73.11 and 6.4.0, an authenticated control panel user with access to Antlers-enabled inputs may be able to achieve remote code execution in the application context. That can lead to full compromise of the application, including access to sensitive configuration, modification or exfiltration of data, and potential impact on availability. Exploitation is only possible where Antlers runs on user-controlled content-for example, content fields with Antlers explicitly enabled (requiring permission to configure fields and to edit entries), built-in config that supports Antlers such as Forms email notification settings (requiring configuration permission), or third-party addons that add Antlers-enabled fields to entries (for example, the SEO Pro addon). In each case the attacker must have the relevant control panel permissions. This has been fixed in 5.73.11 and 6.4.0. Users of addons that depend on Statamic should ensure that after updating they are running a patched Statamic version.

Executive ViewAI

Why It Matters

A high-severity vulnerability in Statmatic CMS could allow authenticated users with specific permissions to execute malicious code on our systems. This poses a critical risk to any organization using Statmatic, as compromised accounts could lead to data theft, system compromise, or operational disruption.

Business Impact: High
Compensating Controls

Apply vendor patch. If immediate patching is not possible: restrict control panel access to essential users only, disable Antlers template engine if not required for operations, implement Web Application Firewall rules to monitor suspicious template injection patterns, and enable enhanced logging and monitoring of control panel activities.

Attack Technique

Code Injection CRITICAL

Code injection occurs when an application accepts user input and passes it directly into a language interpreter or evaluator without proper sanitization.

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
