Upgrade payload to version 3.75.0 or higher.
Overview
payload is a Node, React and MongoDB Headless CMS and Application Framework
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) in the external file upload endpoint due to insufficient validation of HTTP redirects. An attacker can access internal network resources and retrieve response content from internal services by submitting crafted external URLs for file uploads.
Note:
This is only exploitable if at least one collection has upload enabled and the attacker has create access to that upload-enabled collection.
Workaround
This vulnerability can be mitigated by disabling external file uploads via the disableExternalFile upload collection option, or by restricting create access on upload-enabled collections to trusted users only.
