Grav API Plugin Scheduler Command Injection

Publication date: 2026-08-14

Last updated on: 2026-08-14

Assigner: VulnCheck

Description
Grav API plugin versions before 1.0.13 fail to enforce API key scope caps in ConfigController super-scope gates, allowing scoped keys to write scheduler configuration. Attackers with a scoped api.config.write key can inject arbitrary commands into scheduler.custom_jobs that execute via Symfony Process for remote code execution.

Executive Summary

This vulnerability is a Remote Code Execution (RCE) flaw in Grav API Plugin versions before 1.0.13. It occurs because the plugin fails to enforce API key scope restrictions in the ConfigController's super-scope gates. Attackers with a scoped api.config.write key can inject arbitrary commands into the scheduler's configuration, which are then executed via Symfony Process, leading to remote code execution.

Detection Guidance

Check Grav API plugin version with: grep -r "grav-plugin-api" /path/to/grav/install. If version is <= 1.0.12, the system is vulnerable. Inspect API key scopes for users with api.config.write permissions to detect unauthorized scheduler command modifications.

Impact Analysis

If exploited, this vulnerability allows attackers to execute arbitrary commands on the server running the vulnerable Grav instance. This could lead to full system compromise, data theft, or further network infiltration. Systems with internet-facing Grav installations are at highest risk.

Compliance Impact

This vulnerability could lead to unauthorized access, data breaches, or data exfiltration, which would violate compliance requirements under GDPR, HIPAA, and other regulations. Organizations may face fines, legal penalties, and reputational damage if exploited.

Mitigation Strategies

Upgrade grav-plugin-api to version 1.0.13 or later immediately. Review and revoke all scoped API keys with api.config.write permissions. Audit scheduler.custom_jobs for unauthorized commands and restrict super-admin privileges in API controllers.
