CVE-2022-45837Network attack vector

Browser script execution via unescaped request parameter

Published Apr 25, 2023 · Updated Apr 28, 2026

Reflected XSS in Denis 微信机器人高级版 6.0.1 and earlier allows remote attackers to run script in an administrator's browser. The plugin outputs an unsanitized and unescaped request parameter in a generated page; public sources do not identify the parameter or code locus. Exploitation requires a privileged user such as an administrator to open an attacker-controlled request, exposing that user's browser session to script actions.
