WebSocket Security | Breaking Cybersecurity News | The Hacker News

A high-severity security flaw has been disclosed in OpenClaw (formerly referred to as Clawdbot and Moltbot) that could allow remote code execution (RCE) through a crafted malicious link. The issue, which is tracked as CVE-2026-25253 (CVSS score: 8.8), has been addressed in version 2026.1.29 released on January 30, 2026. It has been described as a token exfiltration vulnerability that leads to full gateway compromise. "The Control UI trusts gatewayUrl from the query string without validation and auto-connects on load, sending the stored gateway token in the WebSocket connect payload," OpenClaw's creator and maintainer Peter Steinberger said in an advisory. "Clicking a crafted link or visiting a malicious site can send the token to an attacker-controlled server. The attacker can then connect to the victim's local gateway, modify config (sandbox, tool policies), and invoke privileged actions, achieving 1-click RCE."
