Technical Analysis
The TYPO3 extension "Apache Solr for TYPO3 - Enterprise Search" contains a missing authorization vulnerability (CWE-862) where empty frontend-group and subpage-inheritance restrictions are forcibly applied during indexer sub-requests. This incorrect state is cached in the shared rootline cache, enabling anonymous users to bypass extendToSubpages-inherited access restrictions on cached pages. The vulnerability affects multiple versions of the extension, including >=0 <11.2.8, >=11.5.0 <11.6.6, >=12.0.0 <12.1.4, and >=13.0.0 <13.1.4. The CVSS 4.0 base score is 7.6, indicating high severity, with network attack vector, high complexity, and partial privileges required.
Potential Impact
Anonymous visitors can bypass access restrictions on cached pages that inherit access controls via extendToSubpages, potentially exposing sensitive content that should be restricted. This unauthorized access arises from the persistence of a forged empty frontend-group and subpage-inheritance state in the shared rootline cache.
