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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.33%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
