CVE-2026-47198: Paymenter has URL parameter injection that bypasses paid plan limits at checkout

June 30, 2026

The checkout component improperly filters URL-writable properties, allowing authenticated users to inject arbitrary key-value pairs into server provisioning parameters. Because bundled server extensions prioritize these user-supplied properties over administrator-defined configurations, a regular user can override hosting plans and resource limits at checkout without special privileges.
