CVE-2026-45083: CWE-306: Missing Authentication for Critical Function in intranda goobi-viewer-core
The Goobi viewer is a web application that allows digitised material to be displayed in a web browser. From 4.8.0 to before 26.04.1, the Goobi viewer REST endpoint POST /api/v1/index/stream accepted an arbitrary Solr streaming expression from unauthenticated network clients and forwarded it to the backend Solr server without restriction. An attacker could read the complete Solr index and, in default Solr deployments, also modify or delete indexed records. This vulnerability is fixed in 26.04.1.
AI Analysis
Technical Summary
The Goobi viewer web application exposes a REST endpoint that accepts Solr streaming expressions without authentication, enabling unauthenticated network clients to execute arbitrary Solr queries. This lack of authentication on a critical function (CWE-306) allows attackers to access, modify, or delete Solr index data. The vulnerability affects versions >= 4.8.0 and < 26.04.1 and has a CVSS 3.1 base score of 9.8, indicating critical severity. The vulnerability is resolved in version 26.04.1.
Potential Impact
An attacker can read the complete Solr index and, in default Solr deployments, modify or delete indexed records. This compromises confidentiality, integrity, and availability of the indexed data, potentially leading to data loss or unauthorized data disclosure.
Mitigation Recommendations
This vulnerability is fixed in intranda goobi-viewer-core version 26.04.1. Users should upgrade to this version or later to remediate the issue. No other official remediation or temporary fixes are indicated. Patch status is confirmed by the vendor's versioning information.
