CVE-2026-56093: CWE-639 Authorization Bypass Through User-Controlled Key in TYPO3 Extension "Apache Solr for TYPO3 - Enterprise Search"
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.

Technical Analysis
The TYPO3 extension "Apache Solr for TYPO3 - Enterprise Search" contains an authorization bypass vulnerability (CWE-639) due to the frontend detail-view document lookup not applying siteHash or frontend user access filters. This flaw enables unauthorized retrieval of documents by guessing or obtaining valid Solr document IDs, circumventing access restrictions that are enforced in the standard search functionality. The vulnerability affects multiple versions of the extension, specifically versions >=0 <11.2.8, >=11.5.0 <11.6.6, >=12.0.0 <12.1.4, and >=13.0.0 <13.1.4.
Potential Impact
An unauthenticated attacker can bypass access controls and retrieve documents from the Solr index by exploiting the detail-view document lookup. This could lead to unauthorized disclosure of potentially sensitive information indexed by the search extension. The impact is limited to information disclosure without privilege escalation or code execution.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided in the available data. Until a patch is available, restrict access to the affected extension or disable the vulnerable functionality if possible.
