Description** UNSUPPORTED WHEN ASSIGNED ** Deserialization of Untrusted Data vulnerability in Apache Lucy. This issue affects Apache Lucy: all versions. As this project is retired, we do not plan to release a version that fixes this issue. Users are recommended to find an alternative or restrict access to the instance to trusted users. Lucy is now maintained outside of the ASF at https://github.com/lucysearch . 0.8.0 is no longer affected by this issue, because the offending feature has been removed there. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.
