Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Nanobot's WhatsApp bridge binds WebSocket to **0.0.0.0** (all interfaces) without auth. π₯ **Consequences**: Session hijacking & massive info leakage. Critical severity (CVSS 9.8).
Q2Root Cause? (CWE/Flaw)
π‘οΈ **CWE-306**: Missing Authentication. π **Flaw**: Default config exposes the WebSocket server publicly. No login required to access sensitive bridge functions.
Q3Who is affected? (Versions/Components)
π’ **Vendor**: HKUDS (Data Intelligence Lab@HKU). π¦ **Product**: Nanobot (Lightweight Personal AI Assistant). β οΈ **Status**: Vulnerable versions prior to the fix in v0.1.3.post7.
Q4What can hackers do? (Privileges/Data)
π΅οΈ **Hackers Can**: Hijack active sessions. π€ **Data Impact**: Full read/write access to WhatsApp messages via the bridge. π **Scope**: Remote, no privileges needed.
Q5Is exploitation threshold high? (Auth/Config)
π **Threshold**: LOW. π **Auth**: None required. π **Access**: Network accessible (AV:N). If port is open, anyone can connect.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **PoC**: No specific code snippet provided in data. π **Public Info**: Referenced by Tenable TRA-2026-09. π **Exploitation**: Likely trivial given the lack of auth.
Q7How to self-check? (Features/Scanning)
π **Check**: Scan for open WebSocket ports on Nanobot hosts. π§ͺ **Test**: Attempt direct WebSocket connection without credentials. π‘ **Indicator**: Service bound to 0.0.0.0.
Q8Is it fixed officially? (Patch/Mitigation)
β **Fixed**: Yes. π₯ **Patch**: Upgrade to **v0.1.3.post7** or later. π **Ref**: GitHub release notes from HKUDS.
Q9What if no patch? (Workaround)
π§ **Workaround**: Bind WebSocket to **127.0.0.1** (localhost) only. π **Firewall**: Block external access to the bridge port. π **Auth**: Implement manual auth if binding externally.
Q10Is it urgent? (Priority Suggestion)
π₯ **Priority**: CRITICAL. π¨ **Urgency**: Immediate action required. High CVSS score + no auth = high risk of automated exploitation.
