# RuoYi-Vue: permission service lets a crafted argument escalate privileges

RuoYi-Vue, an open-source Java admin framework, has an improper privilege management flaw in its permission service, function SysPermissionService.getMenuPermission, where the perms argument is not handled safely. A remote attacker may be able to gain privileges beyond what their account allows.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check whether the project in use is RuoYi-Vue and note its version, e.g. `pom.xml` or the project's version file.
- Look for the `SysPermissionService.java` file and the `getMenuPermission` function in the codebase.
