Because user IDs and link-share IDs are independent numeric sequences and both resolve through a generic web.Auth.GetID() interface, a link-share JWT whose numeric ID equals a target user&#39;s ID is treated as that user by the /api/v1/tokens endpoints. An authenticated attacker can obtain a target&#39;s numeric user ID via authenticated user search, then create link shares on an attacker-writable project until the link-share sequence reaches that value, and use the resulting link-share JWT to list, create, and delete the target user&#39;s API tokens (including issuing a new token with attacker-chosen scopes under the target&#39;s permissions). Fixed in version 2.4.0.</p> <p><strong>Affected:</strong> go-vikunja vikunja</p> <p>Vikunja versions 0.22.0 through 2.3.0 fail to validate the principal type in API token management.
