CVE-2026-56093: CWE-639 Authorization Bypass Through User-Controlled Key in TYPO3 Extension "Apache Solr for TYPO3 - Enterprise Search"
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.
AI Analysis
Technical Summary
The TYPO3 extension "Apache Solr for TYPO3 - Enterprise Search" contains an authorization bypass vulnerability (CWE-639) where the frontend detail-view document lookup bypasses siteHash and frontend user access filters. Unlike the regular search path, this lookup allows retrieval of documents by guessing or obtaining valid Solr document IDs without enforcing the same access restrictions. This affects multiple versions including 12.0.0, 13.0.0, and versions prior to 11.6.6, as well as ranges >=12.0.0 <12.1.4 and >=13.0.0 <13.1.4. The vulnerability has a CVSS 4.0 base score of 6.3, indicating medium severity. No official remediation or patch information is currently available.
Potential Impact
An unauthenticated attacker can bypass authorization controls in the affected TYPO3 extension to retrieve documents by guessing or obtaining valid Solr document IDs. This could lead to unauthorized disclosure of information that would otherwise be restricted by site or user access filters.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the affected extension or disable the vulnerable frontend detail-view document lookup if possible to prevent unauthorized document retrieval.
