What is CVE-2026-56092?

This vulnerability arises from the extension's mishandling of frontend-group and subpage-inheritance restrictions during indexer sub-requests. As a result, it allows unauthorized users to circumvent access restrictions on cached pages, potentially exposing sensitive content intended for restricted access. This forged state is inadvertently stored in the shared rootline cache, thus compromising the integrity of the access control mechanisms.

Affected Version(s)

Extension "Apache Solr for TYPO3 - Enterprise Search" 13.0.0 < 13.1.4

Extension "Apache Solr for TYPO3 - Enterprise Search" 12.0.0 < 12.1.4
