{"id":"CVE-2026-55444","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-55444","generatedAt":"2026-10-28T04:18:18.379Z","title":"The Goobi viewer is a web application that allows digitised material to be displayed in a web browser.","description":"The Goobi viewer is a web application that allows digitised material to be displayed in a web browser. 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.","published":"2026-10-23T15:17:33.000Z","lastModified":"2026-10-23T16:28:32.000Z","status":"Deferred","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"},"cwe":["CWE-20","CWE-89","CWE-943"],"affected":[],"epss":{"score":0.00253,"percentile":0.16766,"date":"2026-10-27","history":[{"date":"2026-10-24","score":0.00435,"percentile":0.3676}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.25%).
