OctoPrint vulnerable to possible file extraction via upload endpoints
OctoPrint provides a web interface for controlling consumer 3D printers. OctoPrint versions up until and including 1.11.1 contain a vulnerability that allows an attacker with the FILE_UPLOAD permission to exfiltrate files from the host that OctoPrint has read access to, by moving them into the upload folder where they then can be downloaded from. This vulnerability is fixed in 1.11.2.
