Octoprint

OctoPrint is a widely deployed web-based control and monitoring platform for 3D printers that attracts vulnerability disclosures despite a narrow product footprint, reflecting both its popularity in maker and industrial communities and its direct exposure to network-connected devices. The vulnerability profile centers on authentication and input-handling weaknesses, including cross-site scripting, unverified password changes, authentication bypass via spoofing, and exposure of sensitive information, which are characteristic of web applications that manage device access and user state. A moderate share of the vendor's disclosures reach serious severity levels, and while public exploit code availability remains limited, the nature of these flaws—particularly those affecting authentication and session management—creates material risk in environments where the printer controls are accessible from untrusted networks. Defenders should prioritize inventory of deployed instances, restrict network access to the web interface, and apply updates promptly when authentication or XSS flaws are disclosed. Current severity, exploitation activity, and exposure counts are shown alongside this summary.
