What is CVE-2025-64187?

OctoPrint, a popular web interface for managing 3D printers, is vulnerable to an issue that allows the injection of arbitrary HTML and JavaScript into Action Command notifications. This can be exploited by an attacker to manipulate the printer's actions by convincing a user to run a specially crafted file. Successful exploitation can lead to disruptions in print jobs, unauthorized information access, and potential misuse of user permissions within the OctoPrint platform. The vulnerability affects all versions of OctoPrint up to 1.11.3 but is resolved in version 1.11.4.
