CVE-2026-25505
📋 TL;DR
Bambuddy versions before 0.1.7 have two critical authentication flaws: a hardcoded JWT secret key in source code and missing authentication checks on ManyAPI routes. This allows attackers to forge authentication tokens and access administrative functions without credentials. Anyone running Bambuddy versions 0.1.6 or earlier is affected.
💻 Affected Systems
- Bambuddy
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to access all printer management functions, manipulate print jobs, exfiltrate sensitive data, and potentially pivot to other systems on the network.
Likely Case
Unauthorized access to printer management functions, ability to view/delete print archives, and potential disruption of 3D printing operations.
If Mitigated
Limited to authenticated users only with proper access controls preventing unauthorized API access.
🎯 Exploit Status
The hardcoded secret is publicly visible in GitHub repositories, making token forgery trivial. ManyAPI routes lack authentication checks entirely.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 0.1.7
Vendor Advisory: https://github.com/maziggy/bambuddy/security/advisories/GHSA-gc24-px2r-5qmf
Restart Required: Yes
Instructions:
1. Stop Bambuddy service. 2. Update to version 0.1.7 via package manager or manual installation. 3. Restart Bambuddy service. 4. Verify new version is running.
🔧 Temporary Workarounds
Network Isolation
linuxRestrict network access to Bambuddy to trusted IPs only
iptables -A INPUT -p tcp --dport <bambuddy_port> -s <trusted_ip> -j ACCEPT
iptables -A INPUT -p tcp --dport <bambuddy_port> -j DROP
Reverse Proxy Authentication
allPlace Bambuddy behind a reverse proxy with authentication
🧯 If You Can't Patch
- Immediately isolate Bambuddy from internet access and restrict to internal network only
- Implement network-level authentication (VPN, IP whitelisting) for all Bambuddy access
🔍 How to Verify
Check if Vulnerable:
Check Bambuddy version via web interface or configuration files. If version is 0.1.6 or earlier, system is vulnerable.Check Version:
Check Bambuddy web interface or configuration files for version informationVerify Fix Applied:
Verify version is 0.1.7 or later and test authentication requirements on ManyAPI endpoints.📡 Detection & Monitoring
Log Indicators:
- Unauthorized access attempts to ManyAPI routes
- Authentication failures followed by successful API calls
- JWT token validation failures
Network Indicators:
- Unusual API calls to ManyAPI endpoints without authentication headers
- Requests with forged JWT tokens
SIEM Query:
source="bambuddy" AND (uri="/api/many*" AND NOT auth_token) OR (jwt_validation="failed" AND subsequent_request="successful")
