Account takeover via unchecked password-change mutation

Published Oct 4, 2024 · Updated Oct 4, 2024

Improper access control in Taskcafe 0.3.2 allows remote attackers to take over known user accounts through a GraphQL password change. The updateUserPassword mutation accepts any authToken cookie value and changes the password for the userID supplied in the request body. A registered user's GUID must be known; the new password then grants access to that account, including an administrator account.
