CVE-2022-2872Network attack vector

Stored script execution via unchecked file rename

Published Sep 21, 2022 · Updated May 28, 2025

Unrestricted file upload in OctoPrint before 1.8.3 allows remote authenticated users to create dangerous files through rename operations. The file manager's copy_file and move_file paths accept a destination name without validating its type, so uploaded G-code can be renamed with an HTML extension and served under the OctoPrint origin. A low-privileged account must upload and rename the file, and another user must open it for attacker-controlled script to run in that origin.
