Upgrade OctoPrint to version 1.10.0rc3 or higher.
Overview
OctoPrint is a snappy web interface for your 3D printer
Affected versions of this package are vulnerable to Cross-Site Scripting (XSS) due to the misconfiguration of a webcam snapshot URL which, when tested through the "Test" button in the web interface, will execute JavaScript code in the victim's browser during the attempt to render the snapshot image.
An attacker who successfully convinces a victim with admin rights to perform a snapshot test with a maliciously crafted URL could use this to retrieve or modify sensitive configuration settings, interrupt prints, or otherwise interact with the instance in a malicious manner.
