CVE-2026-56093
Broken Access Control in extension "Apache Solr for TYPO3 - Enterprise Search" (solr)
Description
The extension's frontend detail-view document lookup does not apply the current site's siteHash filter or frontend user access filter, unlike the regular search path. A visitor who can obtain or guess a valid Solr document id can retrieve documents through this lookup without the same access restrictions enforced elsewhere.
