CVE-2026-56096: CWE-943 Improper Neutralization of Special Elements in Data Query Logic in TYPO3 Extension "Apache Solr for TYPO3 - Enterprise Search"
Description
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.

Technical Analysis
The TYPO3 extension "Apache Solr for TYPO3 - Enterprise Search" improperly handles user-supplied search query parameters by passing them directly to Apache Solr without restricting advanced query syntax such as wildcards, field selectors, and range queries. This flaw (CWE-943) allows remote, unauthenticated attackers to enumerate indexed field names and extract stored values using boolean- and range-based blind extraction techniques, regardless of site-specific configurations. The vulnerability affects versions >=0 <11.2.8, >=11.5.0 <11.6.6, >=12.0.0 <12.1.4, and >=13.0.0 <13.1.4.
Potential Impact
An attacker can remotely and without authentication exploit this vulnerability to enumerate sensitive indexed field names and extract their stored values from the Apache Solr index used by the TYPO3 extension. This could lead to unauthorized disclosure of sensitive data indexed by the search engine. The impact is limited to information disclosure and does not include integrity or availability effects.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided in the available data. Until a patch is available, consider restricting or sanitizing user-supplied search query parameters to disallow advanced Solr query syntax such as wildcards, field selectors, and range queries to mitigate the risk of data enumeration.
