CVE-2023-50767Network attack vector

Secret extraction via unauthorized external-entity parsing

Published Dec 13, 2023 · Updated Feb 13, 2025

Missing authorization in Jenkins Nexus Platform Plugin 3.18.0-03 and earlier allows remote authenticated users to extract secrets via crafted XML. Form-validation methods accept an attacker-chosen server URL without an authorization check, then parse the returned XML with external entities enabled. Overall/Read permission is sufficient to make the controller issue the request; a crafted response can read controller secrets or trigger server-side requests.
