Bambuddy grants unauthenticated access after database error

CVE-2026-53459 · published 25 days ago
Summary

If the Bambuddy system cannot talk to its database, it mistakenly lets anyone use any feature without logging in. This can be triggered by sending many requests to a public page, which overloads the database and opens all functions to strangers. Upgrade to version 0.2.4.4 or later to stop this behavior.

Original advisory text
Bambuddy's authentication fails open on database errors, allowing unauthenticated access to all endpoints
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.
