Summary

OctoPrint provides a web interface for controlling consumer 3D printers. OctoPrint versions up until and including 1.10.0 contain a vulnerability that allows an unauthenticated attacker to completely bypass the authentication if the `autologinLocal` option is enabled within `config.yaml`, even if they come from networks that are not configured as `localNetworks`, spoofing their IP via the `X-Forwarded-For` header. If autologin is not enabled, this vulnerability does not have any impact. The vulnerability has been patched in version 1.10.1. Until the patch has been applied, OctoPrint administrators who have autologin enabled on their instances should disable it and/or to make the instance inaccessible from potentially hostile networks like the internet.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
