CVE-2026-94489

Name of the Vulnerable Software and Affected Versions OctoPrint version 1.0.0

Description A path traversal issue exists in the File Download API component within the validate() function of the src/octoprint/server/api/files.py file. A remote attacker can manipulate the filename argument to access files outside the intended directory. Path traversal is a technique used to access files and directories that are stored outside the web root folder.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability. As a temporary workaround, restrict access to the validate() function in the File Download API to minimize the risk of exploitation.
