CVE-2022-41923Public exploitNetwork attack vector

Unauthenticated privilege escalation via mismatched URI authorization

Published Nov 23, 2022 · Updated Apr 23, 2025

Incorrect authorization in the Grails Spring Security Core plugin allows remote attackers to access restricted application endpoints. The calculateUri path derivation can evaluate a crafted request as a donor endpoint for authorization while Grails routes it to a different target endpoint. Exploitation requires an affected application with endpoints having different access rules and can expose or modify resources without interrupting service.
