Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache Solr (solr-core) versions 6.6 through 9.7.0 are affected when running on Windows. The configset upload API does not sanitize input, so a maliciously crafted ZIP file with relative paths can write files to unintended locations on the filesystem. The source does not state what privileges an attacker needs to use the upload API. Upgrade to solr-core 9.8.0, which fixes the issue; users who cannot upgrade can restrict access to the configset upload API to trusted administrators using the Rule-Based Authentication Plugin.
