What is GHSA-vx3h-qwqw-r2wq?
GHSA-vx3h-qwqw-r2wq is a server-side request forgery vulnerability in inventree, published on 2 Oct 2024. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
Impact
The "download image from remote URL" feature can be abused by a malicious actor to potentially extract information about server side resources. Submitting a crafted URL (in place of a valid image) can raise a server side error, which is reported back to the user.
This error message may contain sensitive information about the server side request, including information about the availability of the remote resource.
Patches
The solution to this vulnerability is to prevent the server from returning any specific information about the observed exception. Instead, a generic error message is returned to the client.
This patch has been applied to the upcoming 0.17.0 release, and also back-ported to the 0.16.5 stable release.
Workarounds
To avoid this issue with unpatched versions, the "download image from remote URL" feature can be disabled in InvenTree, preventing users from accessing this information.
