Description
A deserialization vulnerability exists in Jenkins versions 2.587 and earlier, including LTS 2.580.1 and earlier, where the deserialization filter does not apply to classes referenced by the 'resolves-to' attribute during XStream deserialization. This could potentially allow unsafe deserialization of untrusted data.
