Api-Plugin

Grav API Plugin versions prior to 1.0.10 contain a missing authorization vulnerability (CVE-2026-65895) allowing authenticated users with the 'api.config.write' privilege to modify critical security settings, including disabling site-wide rate limiting to enable credential brute-forcing attacks and reconfiguring CORS policies to include attacker-controlled origins with credentials enabled, potentially leading to unauthorized data access.

A critical vulnerability, CVE-2026-58656, in the Grav API plugin before v1.0.0-rc.16 allows unauthenticated attackers to perform fully authenticated cross-origin API requests by leveraging leaked JWT tokens via the `?token=` URL query parameter and the `Access-Control-Allow-Origin: *` response header, potentially leading to persistent backdoor super-admin accounts and sensitive data exfiltration.
