🔬 Technical Analysis

#

Impact OctoPrint versions up until and including 1.11.7 as well as 2.0.0rc1 and 2.0.0rc2 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 was already reported as [GHSA-m9jh-jf9h-x3h2/CVE-2025-48067](https://github.com/OctoPrint/OctoPrint/security/advisories/GHSA-m9jh-jf9h-x3h2) but the fix provided in OctoPrint 1.11.2 turned out to be incomplete. The primary risk lies in the potential exfiltration of secrets stored inside OctoPrint's config, or further system files. By removing important runtime files, this could also be used to impact the availability of the host after an attempted server
