CVE-2026-61450 getgrav CVE debrief

Who should care

Administrators and users of Grav versions prior to 2.0.2 should be aware of this vulnerability and take immediate action to patch their installations. Additionally, security teams and researchers should be aware of the potential impact of this vulnerability and take steps to identify and remediate affected systems.

Technical summary

The vulnerability exists due to an incomplete fix for a previous issue (GHSA-j274-39qw-32c9). Although the sandbox replaces the 'config' variable with a redacted facade and strips Config::get/toArray from the method allowlist, the raw container remains accessible via the allow-listed grav.offsetGet('config'). This allows an attacker to serialize the real Config object at the PHP level without invoking the sandbox method gate, exposing the full config tree including sensitive information.

Defensive priority

Recommended defensive actions

• Apply the official patch (Grav 2.0.2 or later) to fix the vulnerability.
• Review and update configuration secrets, such as SMTP credentials, API keys, and plugin DB credentials, to prevent unauthorized access.
• Implement additional security measures, such as monitoring and logging, to detect potential exploitation attempts.
• Conduct a thorough inventory of affected systems and prioritize patching based on risk and exposure.
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance.
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.
