Disclosure summary
### Impact A user with query access could use polymorphic join filters to infer hidden or read-restricted field values, including password-reset tokens. You are affected if: - You use an affected Payload version. - Users can query a collection with a polymorphic join to sensitive fields. ### Patches Users should upgrade Payload packages to `>= 3.90.0` or `>= 4.0.0-canary.34`. ### Workarounds There is no complete workaround. Restricting read access to sensitive collections reduces exposure but does not replace upgrading.
