HIGHPre-NVD 8.18.1—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 78% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Grav API Plugin is a RESTful API for Grav CMS that provides full headless access to your site's content. Prior to 1.0.6, the Grav API plugin ApiKeyManager::generateKey() stores a declared scopes array, but ApiKeyAuthenticator::authenticate() does not read keyData[scopes] and returns the owning user's complete identity. AbstractApiController::requirePermission() consequently evaluates the full user ACL, so a key issued for a read-only scope can perform every write, delete, and administrative operation available to the owner. This issue is fixed in version 1.0.6.
