Medium (4.6) in octoprint octoprint. EPSS 0.2% chance of exploitation in the next 30 days. Fixed in octoprint 1.11.4.
OctoPrint provides a web interface for controlling consumer 3D printers. Versions 1.11.3 and below are affected by a vulnerability that allows injection of arbitrary HTML and JavaScript into Action Command notifications and prompts popups generated by the printer. An attacker who successfully convinces a victim to print a specially crafted file could exploit this issue to disrupt ongoing prints, extract information (including sensitive configuration settings, if the targeted user has the necessary permissions for that), or perform other actions on behalf of the targeted user within the OctoPrint instance. This issue is fixed in version 1.11.4.
