Description

Jenkins Script Security Plugin versions 1399.ve6a_66547f6e1 and earlier do not perform a permission check in an HTTP endpoint. This allows attackers with Overall/Read permission to enumerate pending and approved Script Security classpaths. Script Security Plugin 1402.v94c9ce464861 requires Overall/Administer permission to enumerate pending and approved Script Security classpaths.
