{"id":"CVE-2026-55442","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-55442","generatedAt":"2026-10-28T02:20:06.494Z","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. 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.","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-116"],"affected":[],"epss":{"score":0.00262,"percentile":0.17871,"date":"2026-10-26","history":[{"date":"2026-10-24","score":0.0045,"percentile":0.38162}]},"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 (0.26%).
