Published Aug 14, 2026CWE-862EPSS 0.33%

Overview

CVE-2026-72823 is a medium-severity vulnerability. It was published on August 14, 2026 and has a CVSS 3.1 base score of 5.4 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.4, rated MEDIUM. 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 DemoController. Its private requireSuper() method checks isSuperAdmin() and returns early before invoking requirePermission(), so the api_key_scopes cap (enforced only in requirePermission()) is skipped. As a result, any scoped API key minted on a super account can bypass its scope restrictions when calling the baseline() and reset() operations (e.g. POST /api/v1/demo/reset), allowing it to capture the demo baseline or force a demo reset. Impact is bounded to demo-engine control and is conditional on demo mode being configured with writable resources.

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.
