CVE-2025-13426Network attack vector

Authenticated code execution via sandbox permission bypass

Published Dec 5, 2025 · Updated Dec 8, 2025

Code injection in Google Cloud Apigee hybrid JavaCallout allows remote authenticated users to execute arbitrary Java and system commands. The runtime insufficiently contains attacker-written JavaCallout objects, allowing reflection or forged permission objects to bypass the security manager. Exploitation requires internal authorization to deploy proxies and grants runtime code execution that exposes data and reachable backend systems.
