Q: Who is affected? (Versions/Components)

🏢 **Vendor**: OpenClaw. 📦 **Product**: nextcloud-talk integration. 📅 **Affected**: Versions **prior to 2026.2.6**. ✅ **Fixed**: 2026.2.6 and later.

Q: Is exploitation threshold high? (Auth/Config)

📉 **Threshold: LOW**. 🔑 **Auth**: No authentication required (PR:N). 🖱️ **UI**: No user interaction needed (UI:N). 🌐 **Network**: Remote exploit (AV:N). ⚡ **Complexity**: Low (AC:L). Easy to exploit!

Q: Is there a public Exp? (PoC/Wild Exploitation)

🚫 **Public Exploit**: No PoC provided in data. 📜 **References**: GitHub Advisory & VulnCheck details exist. 🌍 **Wild Exploit**: Unconfirmed, but low barrier suggests high risk of rapid exploitation.

Q: How to self-check? (Features/Scanning)

🔍 **Check**: Scan for OpenClaw/Nextcloud Talk versions < 2026.2.6. 📋 **Audit**: Review `actor.name` validation logic in code. 🛠️ **Tools**: Use VulnCheck or GitHub Security Advisories for detection.

Q: Is it fixed officially? (Patch/Mitigation)

✅ **Fixed**: Yes. 📥 **Patch**: Upgrade to **OpenClaw 2026.2.6+**. 🔗 **Commit**: See GHSA-r5h9-vjqc-hq3r for official fix details. 🔄 **Action**: Immediate update required.

Q: What if no patch? (Workaround)

🚧 **Workaround**: If unpatched, **disable** Nextcloud Talk integration temporarily. 🛑 **Restrict**: Block external access to the AI service. 👮 **Monitor**: Log all `actor.name` changes for anomalies.

Q: Is it urgent? (Priority Suggestion)

🔥 **Urgency: CRITICAL**. 🚨 **Priority**: Patch Immediately. ⏳ **Risk**: CVSS 9.8 + Low Exploit Difficulty = High likelihood of active abuse. 📢 **Action**: Treat as top-tier emergency.
