Summary
Jenkins, an open-source automation server, is affected by this vulnerability. Because its deserialization filter is not applied to classes referenced by the `resolves-to` attribute during XStream deserialization, an attacker who can supply crafted data could potentially cause the server to load unintended classes, which may lead to arbitrary code execution.
Summarized by anthropic/claude-haiku-5.5. Verify details against the original sources.
