Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache Solr versions from 6.6.0 before 8.11.4 and from 9.0.0 before 9.7.0 are affected. ConfigSets created through a Restore command are not marked as "trusted", and a missing flag is treated as trusted, so an unauthenticated user may be able to get a trusted ConfigSet that loads custom code. Upgrade to 8.11.4 or 9.7.0; Solr instances secured with authentication and authorization are not affected.
