CVE-2026-62667: CWE-862: Missing Authorization in getgrav grav-plugin-api
A missing authorization vulnerability exists in the Grav API Plugin prior to version 1.0.6. The plugin's ApiKeyAuthenticator does not properly enforce scope restrictions, allowing API keys intended for limited read-only access to perform all actions available to the owning user, including write, delete, and administrative operations. This issue is resolved in version 1.0.6.
AI Analysis
Technical Summary
The Grav API Plugin (grav-plugin-api) before version 1.0.6 suffers from a missing authorization check (CWE-862). Although ApiKeyManager::generateKey() stores scopes for API keys, ApiKeyAuthenticator::authenticate() ignores these scopes and returns the full user identity. Consequently, AbstractApiController::requirePermission() evaluates the full user ACL, enabling API keys issued with restricted scopes to perform all actions available to the user, including unauthorized write and administrative operations. This vulnerability has a CVSS 3.1 score of 8.1 (high severity) and is fixed in version 1.0.6.
Potential Impact
An attacker with an API key scoped for limited read-only access can perform unauthorized write, delete, and administrative actions as the owning user. This leads to a high impact on confidentiality and integrity, allowing unauthorized modification of site content. Availability impact is not indicated.
Mitigation Recommendations
Upgrade the Grav API Plugin to version 1.0.6 or later, where this authorization issue is fixed. No other mitigation or workaround is indicated. Patch status is not explicitly stated but the fix is confirmed in version 1.0.6.
