## Affected

- dromara lamp-cloud: through 5.10.0

## Description

lamp-cloud through 5.10.0 whitelists the path pattern /*/anno/** for anonymous access, allowing unauthenticated attackers to read the server's full JVM system property map. Attackers can send POST requests to /defGenProject/anno/getProperties to retrieve sensitive information including JVM classpath, filesystem paths, operating system details, and startup secrets.
