CVE-2026-80204: Incorrect Authorization in getgrav grav
Description
CVE-2026-80204 is a critical authorization vulnerability in the Grav API plugin (getgrav/grav-plugin-api) before version 1.0.18. The flaw occurs because the injectSecurityTab() function in BlueprintController does not enforce API-key scope restrictions when determining if a page's security permissions section is editable. This allows an attacker with a scoped API key to potentially view and edit page permission fields beyond their granted scope. The full impact on write operations has not been confirmed.

Technical Analysis
The Grav API plugin before 1.0.18 contains an authorization bypass vulnerability in the injectSecurityTab() function of BlueprintController. This function fails to apply the API-key scope capability checks properly because it uses raw isSuperAdmin() and hasPermission() calls without passing the request parameter, thus bypassing scopeAllows() enforcement. Consequently, a caller with a scoped API key may access and possibly modify page permission fields outside their authorized scope. The vulnerability has a CVSS 4.0 score of 9.3, indicating critical severity. No patch or official remediation has been confirmed or published at this time.
Potential Impact
An attacker possessing a scoped API key can bypass intended authorization restrictions and access or potentially modify page permission fields beyond their granted scope. This could lead to unauthorized privilege escalation or unauthorized changes to page security settings. The exact extent of write-time impact remains unconfirmed.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict API key usage to trusted users and monitor for suspicious activity related to API key permissions. Avoid using scoped API keys in untrusted environments.
