Vulnerability Assessment

Weakness	CWE CWE-306 OWASP Top 10:2025 A07:2025 - Authentication Failures ASVS 5.0 V6 - Authentication Authentication required for critical functions MITRE ATT&CK 1 technique across 1 tactic: Initial Access The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up.

Exploitation Conditions	Bambuddy versions prior to 0.1.7 with exposed source code repository or compiled artifacts containing hardcoded JWT secret. Default deployment without additional authentication layers on API routes.
Impact	CVSS 9.8 with PoC and patch. 3D printer management with no auth could enable unauthorized printing, modification of print files, or abuse of printer hardware.
Exploit ScenarioDerived	An attacker accesses the unauthenticated Bambuddy interface to start prints, modify STL files, or exfiltrate proprietary 3D designs from the archive.

CRITICAL 9.8

DescriptionGitHub Advisory

Bambuddy is a self-hosted print archive and management system for Bambu Lab 3D printers. Prior to version 0.1.7, a hardcoded secret key used for signing JWTs is checked into source code and ManyAPI routes do not check authentication. This issue has been patched in version 0.1.7.

Executive ViewAI

Why It Matters

Bambuddy versions 0.1.7 and earlier contain a critical authentication bypass vulnerability (CVSS 9.8) that allows unauthenticated attackers to access sensitive functions. This poses an immediate risk to any organization using affected versions, as attackers can exploit this flaw without credentials to compromise data or system integrity. Immediate patching is required to prevent potential exploitation.

Business Impact: Severe

Compensating Controls

Apply vendor patch.
