CVE ID :CVE-2026-55652

Published : July 15, 2026, 10:17 p.m. | 1 hour, 17 minutes ago

Description :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.

Severity: 9.8 | CRITICAL
