CVE-2026-65895

Grav API Plugin versions before 1.0.10 fail to restrict write access to security-critical plugin configuration scopes, allowing authenticated users with api.config.write privilege to modify rate limiting and CORS settings. Attackers can disable rate limiting site-wide to enable credential brute-forcing attacks and reconfigure CORS policies to include attacker-controlled origins with credentials enabled.
