Information Disclosure in extension "Apache Solr for TYPO3 - Enterprise Search" (solr)

Published Aug 25, 2026 · Updated Sep 17, 2026 · Assigned by TYPO3

Vendor: TYPO3 Product: Extension "Apache Solr for TYPO3 - Enterprise Search" Category: Web / CMS

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.
