Summary
Arduino Create Agent is a package to help manage Arduino development. The vulnerability affects the endpoint `/v2/pkgs/tools/installed`. A user who has the ability to perform HTTP requests to the localhost interface, or is able to bypass the CORS configuration, can escalate his privileges to those of the user running the Arduino Create Agent service via a crafted HTTP POST request. This issue has been addressed in version `1.3.3`. Users are advised to upgrade. There are no known workarounds for this issue.
