Payload external upload trust validation issue
Impact
Under certain external upload configurations, Payload could send authentication data to a destination that was not verified as trusted. If the affected request contained a valid session, this could expose that session to an unintended recipient.
You are affected if:
- You have enabled external URL-based upload retrieval, where authenticated requests can trigger it.
Patches
Payload now validates the destination before forwarding authentication data and reapplies that validation when a request changes destination.
Users should upgrade Payload packages to >= 3.90.0 or >= 4.0.0-canary.34.
Workarounds
It is recommended to update all Payload packages to >= 3.90.0 or >= 4.0.0-canary.34.
If you cannot, a valid workaround exists:
- Disable external URL-based upload retrieval where practical.
- If you cannot disable it, configure the upload header filter to remove authentication data from outbound file requests.
- Restrict access to the affected upload functionality.
