CVE-2026-55652

Wekan: Header-login IP allowlist bypass via X-Forwarded-For spoofing in Wekan allows unauthenticated full account takeover (incl. admin)

Wekan is open source kanban built with Meteor. Prior to 9.46, header-login with HEADERLOGINTRUSTEDIPS 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 HEADERLOGINID for any username and receive a meteorlogin_token session, including for admin. This issue is fixed in version 9.46.
