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.","state":0,"publishedAt":"2026-10-23T14:14:26.455+00:00","modifiedAt":"2026-10-23T14:14:26.455+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\": \">= 23.03, < 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-2r24-qxpf-cj65","https://github.com/intranda/goobi-viewer-core/commit/330da2f8255a9ed2200ba46b98bb9b6a88748a4e","https://github.com/intranda/goobi-viewer-core/commit/5a59ffa5d76169a4ad3cc396023ad4a4eca217da","https://github.com/intranda/goobi-viewer-core/releases/tag/v26.05"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-55442","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-55442","identifiers":["CVE-2026-55442"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
