Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache Solr (solr-core) versions 8.10.0 through 8.11.2 and 9.0.0 before 9.3.0 are vulnerable. An unauthenticated attacker with network access to the Schema Designer can use a configSet they created to load external libraries, which can lead to remote code execution. Upgrade to 9.3.0 or 8.11.3, which fix the issue.
