CVE-2026-62667: CWE-862: Missing Authorization in getgrav grav-plugin-api
Description
CVE-2026-62667 is a missing authorization vulnerability in the Grav API Plugin for Grav CMS versions prior to 1.0.6. The flaw allows an API key issued with limited scopes to bypass scope restrictions and perform all actions available to the owning user, including write, delete, and administrative operations. This occurs because the authentication process does not properly enforce declared scopes, leading to excessive permissions. The issue is fixed in version 1.0.6.

Technical Analysis
The Grav API Plugin (grav-plugin-api) prior to version 1.0.6 contains a missing authorization vulnerability (CWE-862). The ApiKeyManager::generateKey() function stores an array of declared scopes for an API key, but the ApiKeyAuthenticator::authenticate() function ignores these scopes and returns the full user identity. Consequently, AbstractApiController::requirePermission() evaluates the full user access control list (ACL), allowing API keys intended for limited (e.g., read-only) scopes to perform all operations available to the user, including write, delete, and administrative actions. This vulnerability is addressed in version 1.0.6.
Potential Impact
An attacker with an API key scoped for limited access can perform unauthorized actions with the full privileges of the owning user, including modifying or deleting content and performing administrative operations. This leads to a high impact on confidentiality and integrity, but no impact on availability is reported.
Mitigation Recommendations
Upgrade the Grav API Plugin to version 1.0.6 or later, where this authorization issue is fixed. No other mitigation is required as the fix is official and addresses the root cause.
