CVE-2026-80204 — MEDIUM (5.4)

Vulnerability Description

The Grav API plugin (getgrav/grav-plugin-api) before 1.0.18 does not apply the API-key scope cap in the injectSecurityTab() function of BlueprintController when deciding whether a page's security/permissions blueprint section is editable. Because the function performs raw isSuperAdmin()/hasPermission() checks without a request parameter, it cannot enforce scopeAllows(). A caller holding a scoped API key may therefore see (and potentially edit) page permission fields beyond the scope granted to the key. The end-to-end write-time impact was not fully confirmed by the reporter.
