GHSA-vc4h-q48j-5hcx: Payload: Field access control bypass on auth collections
Filed UTCSource GTH ↗
Payload's duplicate operation copies field values from the source document even when a field is hidden, or its access.read or access.create rule would reject the value for that caller. The disableDuplicate collection setting, enabled by default on auth collections, did not stop this. ## Patches Users should upgrade Payload packages to >= 3.90.0 or >= 4.0.0-canary.34. ## Workarounds Add a beforeDuplicate field hook to fields and set the value to empty or your default value.
