CVE-2021-36471Network attack vector

Dashboard fingerprinting via exposed demo pages

Published Feb 7, 2023 · Updated Apr 23, 2025

Information exposure in AdminLTE 3.1.0 allows remote attackers to identify deployed dashboards through publicly reachable demo-page URLs. Production deployments copy the intentionally shipped index2.html and index3.html examples into public web roots without any traversal sequence or untrusted pathname resolution. The upstream project disputes the CVE because only misconfigured deployments expose the pages, and no AdminLTE privilege escalation or arbitrary-file access is established.
