Impact
A Server-Side Request Forgery (SSRF) vulnerability exists in Payload's external file upload functionality. When processing external URLs for file uploads, insufficient validation of HTTP redirects could allow an authenticated attacker to access internal network resources.
Users are affected if ALL of these are true:
- Payload version < v3.75.0
- At least one collection with
uploadenabled - A user has
createaccess to that upload-enabled collection
An authenticated user with upload collection write permissions could potentially access internal services. Response content from internal services could be retrieved through the application.
Patches
This vulnerability has been patched in v3.75.0. Users should upgrade to v3.75.0 or later.
Workarounds
If users cannot upgrade immediately, they can mitigate this vulnerability by disabling external file uploads via the disableExternalFile upload collection option, or by restricting create access on upload-enabled collections to trusted users only.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker needs high-level or administrative privileges. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a high impact on the confidentiality of the information. There is a high impact on the integrity of the data.
Exploitation attempts have been detected. Elevated vigilance and prompt remediation are advised.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
