CVE-2026-31843 is a critical remote code execution vulnerability in the goodoneuz/pay-uz Laravel package affecting versions up to and including 2.2.24. The flaw resides in the payment editable update API endpoint, which is exposed through a route accepting arbitrary HTTP methods and is not protected by authentication middleware. An unauthenticated remote attacker can supply content that is written directly into existing PHP payment hook files via file_put_contents(). Those modified hook files are subsequently loaded with require() during normal payment processing, causing attacker-controlled PHP code to execute under the application’s default behavior.
