This vulnerability affects the endpoint `/upload` which handles request with the `filename` parameter.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.35%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Arduino Create Agent is a package to help manage Arduino development. This vulnerability affects the endpoint `/upload` which handles request with the `filename` parameter. A user who has the ability to perform HTTP requests to the localhost interface, or is able to bypass the CORS configuration, can escalate their privileges to those of the user running the Arduino Create Agent service via a crafted HTTP POST request.
