Overview

CVE-2026-72824 is a high-severity vulnerability. It was published on August 14, 2026 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

The Grav API plugin (getgrav/grav-plugin-api) before 1.0.13 contains an API key scope-cap bypass in PagesController::guardTwigContent(). The Twig-toggle check uses a bare isSuperAdmin() gate that does not consult api_key_scopes, so a least-privilege API key scoped only to api.pages.write and minted on a super account can enable process.twig on a page save even though admin.pages_twig is intentionally outside the api.pages scope. When security.twig_content.process_enabled=true and editor_enabled=false, this allows Twig-in-content to execute server-side, resulting in server-side template injection (SSTI) and remote code execution.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
