{"schema":"threatline.record/2","record":{"id":"CVE-2026-55442","aliases":["GHSA-2r24-qxpf-cj65"],"summary":"Goobi viewer: cleanUpQuery double-brace bypass allows arbitrary Solr local-param injection","details":"The Goobi viewer is a web application that allows digitised material to be displayed in a web browser. From version 23.03 to before version 26.05, SolrTools.cleanUpQuery() strips Solr local-parameter syntax ({!...}) from user-supplied query strings before they reach Solr. Its regex can be bypassed by wrapping the local parameter in a second pair of curly braces ({{!...}}): the outer braces are stripped, the inner {!...} survives intact, and a valid Solr local parameter is forwarded. The flaw is in the shared sanitizer, so it affects any endpoint that routes user input through cleanUpQuery. The double-brace bypass applies from v23.10 (the greedy \\{(.+)\\} regex); a related bare-!join rewrap path is present. 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-2026-55442","source_modified_at":"2026-10-23T14:14:26.455Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"goobi-viewer-core","vendor":"intranda","versions":[{"status":"affected","version":">= 23.03, < 26.05"}],"defaultStatus":null}],"fixed_versions":[],"cvss":5.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.0045,"percentile":0.38162,"score_date":"2026-10-24"},"published_at":"2026-10-23T14:14:26.455Z","modified_at":"2026-10-23T14:14:26.455Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-55442","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23T14:14:26.455Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-55442","fetched_at":"2026-10-24T18:03:20.872036Z","source_modified_at":"2026-10-24"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/intranda/goobi-viewer-core/security/advisories/GHSA-2r24-qxpf-cj65","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/intranda/goobi-viewer-core/commit/330da2f8255a9ed2200ba46b98bb9b6a88748a4e","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/intranda/goobi-viewer-core/commit/5a59ffa5d76169a4ad3cc396023ad4a4eca217da","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":"2026-10-23T14:14:26.455Z","content_hash":"7920ba79e871c8e8481c775954472dbbb78081afc6f4221580a9ce1f61aa6b05"}}
