Paid plan bypass via URL-injected provisioning properties
Published Jul 20, 2026 · Updated Jul 20, 2026
Improper input validation in Paymenter before 1.5.1 allows remote authenticated users to override paid hosting resource limits at checkout. The Checkout Livewire component exposes checkoutConfig through the config URL parameter, validates only extension-declared keys, and stores every remaining key. Exploitation requires a regular account and an active server extension that prioritizes stored properties, enabling overrides of CPU, RAM, storage, or package tiers.
