CVE-2025-14856Public exploitNetwork attack vector

Authenticated code execution via Thymeleaf fragment injection

Published Dec 18, 2025 · Updated Dec 18, 2025

Server-side template injection in RuoYi 4.8.0 through 4.8.1 allows remote authenticated users to execute code via a crafted fragment. CacheController.getCacheNames concatenates the fragment parameter into the Thymeleaf view selector, causing template preprocessing to evaluate injected expressions. Access requires the monitor:cache:view permission; successful exploitation can execute operating-system commands in the server process.
