Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The npm package payload, in versions before 3.90.0 and in 4.0.0-canary releases before 4.0.0-canary.34, did not correctly enforce a field-level access.update restriction on the password field of an auth collection. The source does not say what kind of access an attacker needs or what exact changes they could make. Users should upgrade to payload 3.90.0 or 4.0.0-canary.34 or later.
