Information disclosure via unrestricted Solr query syntax
Published Aug 25, 2026 · Updated Aug 25, 2026
Information disclosure in Apache Solr for TYPO3 allows remote attackers to extract indexed field values through crafted search queries. The extension forwards the search query parameter to Solr without restricting wildcards, field selectors, or range expressions, enabling blind field enumeration and value extraction. No authentication or site-specific configuration is required, and the documented consequence is disclosure of data stored in the search index.
