CVE-2026-75836 getgrav CVE debrief

Who should care

Defenders responsible for Grav installations, particularly those using plugins that rely on the documented authorize semantics, should assess exposure and verify the authorization requirements for their plugins.

Why it matters

The vulnerability in the Grav API plugin allows authenticated callers to bypass authorization and invoke privileged menubar actions, potentially leading to unauthorized changes or actions.

• Verification of plugin authorization requirements is necessary to prevent unauthorized actions.
• Defenders must ensure that the plugin version is 1.0.14 or later to address the vulnerability.
• Monitoring for suspicious activity related to menubar actions is recommended.

Technical summary

The Grav API plugin before version 1.0.14 fails to enforce the authorize requirement in MenubarController::executeAction(), allowing authenticated callers with api.access to invoke privileged menubar actions directly. This vulnerability affects any first- or third-party plugin relying on the documented authorize semantics. On a stock install, the impact is latent; defenders should verify plugin authorization requirements and ensure version 1.0.14 or later is used to address the vulnerability and monitor for suspicious activity.

Defensive priority

Defenders should prioritize verifying the authorization requirements for plugins using the Grav API and ensure that the plugin version is 1.0.14 or later.

Recommended defensive actions

• Verify the authorization requirements for plugins using the Grav API
• Ensure that the plugin version is 1.0.14 or later
• Monitor for any suspicious activity related to menubar actions
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes

The CVE record and NVD entry provide details about the vulnerability in Grav API plugin before version 1.0.14, which fails to enforce the authorize requirement in MenubarController::executeAction(). The scope of affected plugins and versions requires further verification, particularly for those relying on documented authorize semantics. Defenders should verify plugin authorization requirements and ensure version 1.0.14 or later is used, monitoring for suspicious activity related to menubar actions.
