Goobi Viewer 是一款允许在 Web 浏览器中展示数字化资源的 Web 应用程序。在版本 23.03 至 26.05（不含）之间， 方法会在用户提交的查询字符串到达 Solr 之前，剥离其中的 Solr 本地参数语法（即 ）。然而，该方法的正则表达式可通过将本地参数包裹在第二层花括号（即 ）来绕过：外层花括号会被移除，而内层的 保持完整，从而使得有效的 Solr 本地参数得以通过。该漏洞存在于共享的清理（sanitizer）组件中，因此会影响所有将用户输入交由 处理的接口。双重花括号绕过方式自 v23.1

Vulnerability Title
Goobi viewer: cleanUpQuery double-brace bypass allows arbitrary Solr local-param injection
Source: CVE Program / CVE List V5
Vulnerability 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.
