Grav CMS Static Method Call Arbitrary File Read

Publication date: 2026-08-03

Last updated on: 2026-08-03

Assigner: VulnCheck

Description
Grav CMS versions 2.0.7 through 2.0.10 fail to validate fully-qualified static method calls (Class::method) in blueprint dynamic-field directives because Blueprint::isSafeDynamicCall() only applies its dangerous-callable denylist to strings that do not contain '::'. An account with only page-editing rights (admin.pages, not super-admin or admin.pages_twig) can plant a directive in a page's form-field frontmatter that invokes an arbitrary public static PHP method with attacker-controlled arguments. Using built-in gadget methods this allows reading of any server-readable file (disclosed to anonymous visitors of the crafted page) and arbitrary creation/copying of files and directories under the web-server account. Fixed in 2.0.11.

Executive Summary

Grav CMS versions 2.0.7 through 2.0.10 have a flaw where static method calls in blueprint dynamic-field directives are not fully validated. An attacker with page-editing rights can exploit this to invoke arbitrary public static PHP methods with controlled arguments, leading to file read and write access on the server.

Detection Guidance

Check Grav CMS version with 'composer show grav/grav' or 'bin/grav version'. If version is between 2.0.7 and 2.0.10, the system is vulnerable. Inspect blueprint files for dynamic-field directives containing '::' to identify potential malicious static method calls.

Impact Analysis

An attacker could read sensitive files on your server or create/modify files and directories under the web server account. This could lead to data breaches, unauthorized access, or further compromise of the system.

Compliance Impact

This vulnerability could lead to unauthorized data access or exposure, violating GDPR's data protection principles or HIPAA's security requirements for protected health information. Compliance may be compromised if sensitive data is accessed or leaked.

Mitigation Strategies

Upgrade Grav CMS to version 2.0.11 or later immediately to patch the vulnerability. Restrict page-editing rights to only trusted users and avoid granting admin.pages permissions to untrusted accounts.
