CVE-2025-9321Public exploitNetwork attack vector

Unauthenticated code execution via attacker-selected class instantiation

Published Sep 23, 2025 · Updated Sep 23, 2025

Code injection in WPSight WPCasa 1.4.1 and earlier allows remote attackers to execute arbitrary PHP code through a public API request. The api_requests method treats the wpsight-api query value as a class name, invokes class_exists with autoloading enabled, and instantiates any matching class without an allowlist. No authentication or user interaction is required, and execution depends on a loaded or autoloadable class with attacker-useful constructor behavior.
