Upgrade Bambuddy to version 0.2.4.4 or later, where the authentication fail-open vulnerability is patched. No other mitigation is indicated or required by the vendor advisory.
Description
Bambuddy is a self-hosted print archive and management system for Bambu Lab 3D printers. Starting in version 0.1.6 and prior to version 0.2.4.4, a fail-open in the authentication code allows any attacker to bypass authentication by flooding a public endpoint to exhaust resources causing database access to fail, granting unauthenticated access to all protected endpoints. Version 0.2.4.4 patches the issue.
