Payload is a free and open source headless content management system. In versions from 3.0.0 before 3.90.0 and canary versions before 4.0.0-canary.34, a user who can query a collection with a polymorphic join to sensitive fields can infer hidden or read-restricted values, including password-reset tokens, through polymorphic join filters. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34.
