What fixes it

  • 3.90.0payload, npmGitHubnpm install payload@3.90.0
  • 4.0.0-canary.34payload, npmGitHubnpm install payload@4.0.0-canary.34

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

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.
