CVE-2026-75479Public exploitNetwork attack vector

Unauthenticated report access via leaked share tokens

Published Aug 17, 2026 · Updated Aug 18, 2026

Authentication bypass in JEECG JimuReport 2.3.4 and earlier allows remote attackers to read report metadata and share tokens via the folder template listing endpoint. In DesignReportController, GET /jmreport/query/report/folder/template is marked @JimuNoLoginRequired, and JimuReportTokenInterceptor.preHandle() returns before token validation, so the response exposes each report's shareViewUrl and embedded shareToken. Any network-reachable instance is exposed without credentials; replaying a leaked token against share-accessible endpoints such as /jmreport/show can disclose full report definitions, embedded SQL, and live query results.
