{"schema":"threatline.record/2","record":{"id":"CVE-2026-55444","aliases":["GHSA-763m-wjm9-6873"],"summary":"Goobi viewer: Solr query injection via the legacy RSS servlet q and filterQuery parameters","details":"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.","categories":["Unclassified"],"product":"goobi-viewer-core","vendor":"intranda","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-55444","source_modified_at":"2026-10-23T14:16:16.350Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"goobi-viewer-core","vendor":"intranda","versions":[{"status":"affected","version":"< 26.05"}],"defaultStatus":null},{"source":"GitHub Advisory Database","source_url":"https://github.com/intranda/goobi-viewer-core/security/advisories/GHSA-763m-wjm9-6873","source_modified_at":"2026-06-18T14:42:49Z","fetched_at":"2026-10-24T00:31:04.721601Z","package":{"ecosystem":"maven","name":"io.goobi.viewer:viewer-core"},"range":"<26.05"}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/intranda/goobi-viewer-core/security/advisories/GHSA-763m-wjm9-6873","source_modified_at":"2026-06-18T14:42:49Z","fetched_at":"2026-10-24T00:31:04.721601Z","package":{"ecosystem":"maven","name":"io.goobi.viewer:viewer-core"},"version":"26.05"}],"cvss":5.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-23T14:16:16.350Z","modified_at":"2026-10-23T14:16:16.350Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-55444","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23T14:16:16.350Z"},{"source":"GitHub Advisory Database","url":"https://github.com/intranda/goobi-viewer-core/security/advisories/GHSA-763m-wjm9-6873","fetched_at":"2026-10-24T00:31:04.721601Z","source_modified_at":"2026-06-18T14:42:49Z"}],"sources":["CVE List","GitHub Advisory Database"],"references":[{"source":"CVE List","url":"https://github.com/intranda/goobi-viewer-core/security/advisories/GHSA-763m-wjm9-6873","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/intranda/goobi-viewer-core/commit/e8d987f8478b86559ef3ea236be0d86e08948f6b","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/intranda/goobi-viewer-core/commit/fcdae14b06e99f3320a02d45a6be7fc6e5c69a6e","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/intranda/goobi-viewer-core/releases/tag/v26.05","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-23T14:16:16.350Z","content_hash":"0688189a89f12a204b4f5f8c340ea487d54cadbff4f82708a0dd4dc16a023e95"}}
