🔑 Enhanced Key Takeaways
- •OpenClaw has suffered real-world data leaks including API keys and credentials due to prompt injection via external content like emails and web pages.[1]
- •Security researchers demonstrated indirect prompt injection (CVE-2026-22708) using hidden HTML payloads in webpages to achieve zero-click remote code execution and data exfiltration.[3]
- •ClawHub skill marketplace contains up to 20% malicious skills enabling credential theft and backdoors, amplifying risks in OpenClaw deployments.[2]
🛠️ Technical Deep Dive
- •CVE-2026-22708 exploits unsanitized web content fed into LLM context, using hidden div with opacity:0 containing base64-encoded exfiltration commands triggered via social engineering.[3]
- •CVE-2026-25593 enables local RCE via unauthenticated WebSocket config.apply with malicious cliPath, leading to OS command injection (CWE-78) during command discovery.[6]
- •ClawJacked flaw and log poisoning via TCP port 18789 WebSocket allowed indirect prompt injection by writing malicious logs read by the agent, patched in v2026.2.13.[5]
