Document Access Bypass in Solr Extension

Publication date: 2026-08-25

Last updated on: 2026-08-25

Assigner: TYPO3

Description
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.

Executive Summary

This vulnerability involves a flaw in a frontend document lookup feature that fails to apply site-specific access restrictions. Unlike normal search paths, it does not enforce the current site's siteHash filter or frontend user access controls. This allows unauthorized access to documents if a valid Solr document ID is obtained or guessed.

Impact Analysis

An attacker could exploit this to retrieve sensitive documents without proper authorization. This may lead to unauthorized data exposure, privacy breaches, or compliance violations depending on the document's content.

Compliance Impact

This vulnerability could result in unauthorized access to personal or sensitive data, violating GDPR's data protection principles or HIPAA's access control requirements. Organizations may face legal penalties, reputational damage, and loss of trust.

Mitigation Strategies

Apply the latest security patches or updates for the affected extension. Review and enforce siteHash and frontend user access filters in the document lookup process. Restrict access to Solr document IDs and validate all requests to prevent unauthorized document retrieval.
