CVE-2026-56096: TYPO3 Extension Apache Solr For TYPO3 - Enterprise Search

Medium severity, CVSS 6.3. EPSS: 0.4% chance of exploitation in the next 30 days.

The extension passes the user-supplied search query parameter to Apache Solr without restricting advanced Solr query syntax such as wildcards, field selectors and range queries. A remote, unauthenticated attacker can use this syntax to enumerate indexed field names and extract their stored values through boolean- and range-based blind extraction techniques, independent of any site-specific configuration.
