Prior to version 26.05, the legacy RSS servlet (RssResolver, GET /rss/) accepts the q and filterQuery parameters and concatenates them into Solr queries without validation. The servlet predates the REST API layer and lacks the input validation present in GET /api/v1/records/rss. q forms the main query body (wrapped only in literal parentheses); filterQuery is passed directly as a Solr fq. An unauthenticated attacker can inject Solr boolean operators to break out of the wrapping and render the trailing access-condition filter-query suffix optional, so that access-restricted records are included in the generated RSS feed. The q and filterQuery parameters are the same underlying vulnerability in the same servlet; q (the main query body) has the broader scope. This issue has been patched in version 26.05.","state":0,"publishedAt":"2026-10-23T14:16:16.35+00:00","modifiedAt":"2026-10-23T14:16:16.35+00:00","affected":[{"ecosystem":"Vendor product","name":"goobi-viewer-core","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"intranda\",\n                    \"product\": \"goobi-viewer-core\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 26.05\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3,"severity":"MEDIUM"}],"references":["https://github.com/intranda/goobi-viewer-core/security/advisories/GHSA-763m-wjm9-6873","https://github.com/intranda/goobi-viewer-core/commit/e8d987f8478b86559ef3ea236be0d86e08948f6b","https://github.com/intranda/goobi-viewer-core/commit/fcdae14b06e99f3320a02d45a6be7fc6e5c69a6e","https://github.com/intranda/goobi-viewer-core/releases/tag/v26.05"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-55444","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-55444","identifiers":["CVE-2026-55444"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
