Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Waline's @waline/vercel package is affected in versions before 1.41.0. The login endpoint accepts a non-string email value, which the MongoDB storage adapter silently drops from the query, so the lookup matches all users and checks the submitted password against the first-registered user, typically the site administrator. An unauthenticated attacker who sends such a request can enumerate users and test passwords against the administrator account without knowing its email, and gains administrator login if the password is valid. Upgrade to @waline/vercel 1.41.0 or later.
