CVE-2026-15512Public exploitNetwork attack vector

Authenticated command execution via unsandboxed Velocity templates

Published Jul 12, 2026 · Updated Jul 12, 2026

Server-side template injection in PIGCLOUD Pig 3.9.0 through 3.9.2 allows remote authenticated users to execute arbitrary commands. GeneratorServiceImpl passes database-stored templateCode to VelocityKit, which evaluates it with exposed Java objects and no sandbox, enabling reflection into Runtime.exec. Administrative template-management access and a preview request are required; successful exploitation runs commands in the pig-codegen service context.
