Overview
OctoPrint is a snappy web interface for your 3D printer
Affected versions of this package are vulnerable to User Impersonation via the X-Preemptive-Recording HTTP header. An attacker could bypass the login redirect and directly access the HTML of certain frontend pages by adding the HTTP header X-Preemptive-Recording: yes to HTTP requests.
Notes:
The impact on data exposure is minimal because, typically, data is loaded via API requests that correctly enforce user authentication. The primary risk lies in potential future modifications to the codebase that might incorrectly rely on vulnerable internal functions for authentication checks, leading to security vulnerabilities.
The vulnerability affects the functions
require_login,require_login_with, andrequire_fresh_login_withinoctoprint/server/util/init.pyfile.
