FKIE_CVE-2026-55652

Vulnerability from fkie_nvd - Published: 2026-07-15 22:17 - Updated: 2026-07-16 13:43
Severity
9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
Wekan is open source kanban built with Meteor. Prior to 9.46, header-login with HEADER_LOGIN_TRUSTED_IPS uses getRequestIp() in server/lib/headerLoginAuth.js to trust the client-supplied X-Forwarded-For header before the real socket address, allowing an unauthenticated attacker to send HEADER_LOGIN_ID for any username and receive a meteor_login_token session, including for admin. This issue is fixed in version 9.46.
