Affected versions of this package are vulnerable to Access Control Bypass via the updateDocument function in packages/payload/src/collections/operations/utilities/update.ts, where the password field is extracted and the shouldSavePassword flag is computed before field-level access control is evaluated. This ordering allows an authenticated attacker to update another user's password without having the required update access on the password field, leading to account takeover.
