CVE-2026-56092Network attack vector

Restricted-page disclosure via rootline cache poisoning

Published Aug 25, 2026 · Updated Aug 25, 2026

Missing authorization in Apache Solr for TYPO3 affected releases allows remote attackers to read access-restricted cached pages. During an indexer sub-request, the extension overwrites fe_group and extendToSubpages on page records with public values, which TYPO3 Core persists in the shared rootline cache. Exploitation requires an indexer sub-request to poison the cache; subsequent page access is anonymous and lasts while the forged cache entry survives.
