Authenticated code execution via Enum resolver bypass
Published Aug 31, 2026 · Updated Sep 4, 2026
Server-side template injection in Qute allows remote authenticated users to execute commands through attacker-controlled template text. ReflectionValueResolver fails to block sensitive Java internal methods when resolving certain data types, including Enum values. Exploitation requires permission to supply or modify template content, and commands run in the Java process context, enabling complete application compromise.
