CVE-2026-49396 Details
Description
Nezha Monitoring is a self-hostable, lightweight, servers and websites monitoring and O&M tool. From version 1.0.0 to before version 2.0.14, cross-site GET request can trigger stored cron commands on a victim's agents. This issue has been patched in version 2.0.14.
A cross-site request forgery (CSRF) vulnerability has been identified in Nezha Monitoring versions 1.0.0 prior to 2.0.14. This issue allows an attacker to trigger stored cron commands on a victim's agents by exploiting an authenticated GET endpoint that lacks proper CSRF protection. The vulnerability arises because the 'nz-jwt' cookie, which contains the user's authentication token, is sent with cross-site GET requests, enabling the attacker to manipulate the victim's cron tasks without their consent.
Users are advised to update Nezha Monitoring to version 2.0.14 or later. Additionally, it is recommended to implement CSRF protection for cookie-authenticated state-changing requests and to validate 'Origin' or 'Referer' headers for cross-site requests.
