CVE-2026-52893 Details
Description
Wekan is open source kanban built with Meteor. Prior to 9.32, the Wekan Accounts.onCreateUser hook in server/models/users.js merges OIDC logins into existing accounts when the OIDC email or username matches an existing Wekan user, without verifying ownership or checking email_verified. An attacker using an OIDC provider account with a victim's email or username can cause Wekan to merge the attacker's OIDC credentials into the victim account and then log in as that account. This issue is fixed in version 9.32.
A vulnerability in Wekan's handling of OpenID Connect (OIDC) logins can lead to unauthorized account access. Prior to version 9.32, the 'Accounts.onCreateUser' hook automatically merged OIDC accounts into existing Wekan accounts if the OIDC email or username matched, without verifying ownership or checking if the email was verified. This allowed an attacker to merge their OIDC credentials into a victim's account and gain access to it. The vulnerability affects Wekan versions through 9.31.
Users can update to Wekan version 9.32 or later, where this vulnerability has been fixed. Instructions for downloading the latest version are available on the Wekan GitHub releases page.
