Alert meAnalysisAIv1 – Jul 21, 2026
Broken authorization in the Grav api plugin (grav-plugin-api) before 1.0.8 lets any authenticated panel user holding the baseline admin.login permission forge persistent API keys bound to arbitrary accounts, resulting in impersonation and privilege escalation up to account takeover. The plugin intercepts the apiKeyGenerate/apiKeyRevoke admin tasks ahead of the account-management ACL, so a low-privilege operator can mint a key that inherits a higher-privileged account's API permissions. Reported by VulnCheck with a fix in 1.0.8; no public exploit identified at time of analysis and the flaw is not listed in CISA KEV.

Lifecycle Timeline
2DescriptionCVE.org
The Grav api plugin (grav-plugin-api) before 1.0.8 fails to properly authorize API key generation and revocation: the plugin intercepts the apiKeyGenerate/apiKeyRevoke admin tasks before the account-management ACL runs and authorizes the caller on only the admin.login permission (the baseline permission held by every panel user). This allows any user with admin.login to mint a persistent API key bound to any account, and the forged key inherits the target account's API permissions. On installs where an API-enabled account holds broader permissions, this enables account impersonation and privilege escalation up to account takeover.
Executive ViewAI
The Grav CMS api plugin (grav-plugin-api) before version 1.0.8 contains a broken authorization flaw allowing authenticated panel users with baseline admin permissions to forge persistent API keys for arbitrary accounts, enabling privilege escalation and account takeover (CVSS 8.7). Organizations deploying Grav with this plugin enabled face risk of unauthorized account access if any panel user is compromised or malicious.
Within 24 hours, identify all Grav deployments using grav-plugin-api and confirm installed versions; immediately disable the api plugin on any systems running versions prior to 1.0.8. Within 7 days, upgrade grav-plugin-api to version 1.0.8 across all affected installations and review panel access controls to restrict admin.login permissions to necessary personnel only. Within 30 days, conduct an audit of all API keys in affected Grav instances to identify any unauthorized keys created during the vulnerability window, revoke suspicious keys, and deploy logging to alert on future API key generation outside normal operational patterns.

Authentication bypass attacks exploit flaws in the verification mechanisms that control access to systems and applications.
