CVE-2026-56092: TYPO3 Extension Apache Solr For TYPO3 - Enterprise Search

High severity, CVSS 7.6. EPSS: 0.3% chance of exploitation in the next 30 days.

The extension forces empty frontend-group and subpage-inheritance restrictions onto page records during indexer sub-requests, and this forged state was persisted into the shared rootline cache, allowing anonymous visitors to bypass extendToSubpages-inherited access restrictions on cached pages.
