Lifecycle Timeline
3DescriptionCVE.org
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.
AnalysisAI
Frontend detail-view document lookup in the Apache Solr for TYPO3 Enterprise Search extension bypasses both the siteHash isolation filter and frontend user access controls, allowing retrieval of Solr-indexed documents outside normal authorization constraints. An unauthenticated visitor who obtains or guesses a valid Solr document ID can access content restricted to specific sites or authenticated frontend users by querying the detail-view endpoint directly, circumventing the access controls enforced on the regular search path. …
