CVE-2021-36546Public exploitNetwork attack vector

Unauthenticated log disclosure via exposed runtime path

Published Feb 3, 2023 · Updated Mar 26, 2025

Information disclosure in KiteCMS 1.1 allows remote attackers to read sensitive ThinkPHP log data through a crafted application URL. The web server exposes date-named files beneath /runtime/log/ without access control, and those logs record administrator credentials, actions, and system details. No authentication or user interaction is required; successful requests disclose stored secrets and operational data but do not alter the site.
