CVE-2026-56096: TYPO3 Apache Solr for TYPO3 information disclosure in search query

CVE-2026-56096 · Severity: info · CVSS 7.5 · Published 2026-08-25

The Apache Solr for TYPO3 extension, used to provide search functionality on TYPO3 websites, fails to restrict advanced Solr query syntax in user-supplied search parameters. An unauthenticated attacker can exploit this to enumerate database field names and extract sensitive indexed data through blind search techniques, bypassing any site-specific access controls.

Vendors: Typo3.

Technical details

The vulnerability is an information disclosure issue (CWE-943) in the TYPO3 Apache Solr for TYPO3 extension. The root cause is insufficient input validation: the extension passes user-supplied search query parameters directly to Apache Solr without sanitizing or restricting advanced Solr query syntax (wildcards, field selectors, range queries). An unauthenticated, remote attacker can leverage boolean-based and range-based blind extraction techniques to enumerate indexed field names and extract their stored values. This attack succeeds regardless of site-specific configuration or access controls. No authentication is required, and the attack is network-accessible.
