CVE-2026-4564Public exploitNetwork attack vector

Authenticated code execution via unrestricted reflective invocation

Published Mar 22, 2026 · Updated Mar 22, 2026

Code injection in RuoYi 4.8.0 through 4.8.2 allows remote authenticated users to execute code via a crafted Quartz job invokeTarget value. JobInvokeUtil parses that value as a class and method, instantiates any dotted class name through Class.forName, and invokes the selected public method without an allowlist. Access to scheduled-job administration with high privileges is required; successful execution runs with the RuoYi server process's privileges.
