Open Claw has faced critical security vulnerabilities including CVE-2026-25253 RCE exploit. Learn about risks, malicious skills, industry warnings, and how to use OpenClaw safely with VirusTotal integration and best practices.
Open Claw's powerful capabilities come with significant security considerations. The platform requires broad permissions to function effectively, and its open ecosystem means users must be vigilant about security.
The following critical vulnerabilities have been identified and patched in Open Claw:
One-click remote code execution vulnerability allowing attackers to execute arbitrary code through cross-site WebSocket hijacking. The server did not validate WebSocket origin headers.
✓ Action Required: Update to latest OpenClaw version immediately
Within a 3-day period, multiple high-impact security advisories were released:
The open skills ecosystem has been exploited by malicious actors:
Example Attack: A malicious "weather plugin" was found exfiltrating private configuration files containing API keys and sensitive credentials.
In response to security concerns, Open Claw has partnered with VirusTotal for enhanced security:
Cybersecurity experts and industry leaders have raised significant concerns about Open Claw security:
"Security dumpster fire"
— npm Founding CTO
"Security nightmare"
— Cisco Security Team
"Potential biggest insider threat of 2026"
— Palo Alto Networks
The technology has attracted heavy scrutiny from cybersecurity researchers and technology journalists. Open Claw's security posture remains a topic of active debate in the security community.
Open Claw requires extensive permissions to function effectively. Misconfigured instances pose major security risks:
⚠️ Warning: These broad permissions mean a compromised Open Claw instance gives attackers extensive access to your digital life.
Follow these recommendations to use Open Claw more safely:
Keep OpenClaw at the latest version (v2026.2.6 or newer) to receive security patches.
Inspect skill source code before installing. Only install from trusted sources.
Only install skills that have been scanned by VirusTotal (available in v2026.2.6+).
Never expose http://127.0.0.1:18789/ publicly. Keep it on localhost only.
Ensure origin validation is enabled (fixed in v2026.1.29+) to prevent hijacking.
Review what permissions each skill requests before granting access.
Create separate API keys for OpenClaw with limited scopes and budget caps.
Periodically review installed skills, plugins, and configuration settings.
Run Open Claw on an isolated network if handling sensitive data.
Maintain backups of SOUL.md and other configuration files.
On January 31, 2026, 404 Media reported a critical vulnerability in the Moltbook platform:
The Open Claw team is actively working on security improvements:
Automated skill scanning with Google's threat intelligence platform (Feb 2026)
Built-in scanner for skill analysis and threat detection (v2026.2.6)
WebSocket origin validation to prevent hijacking attacks
Granular permission controls for skills and plugins
Isolated execution environment for untrusted skills
Continuous security review and vulnerability disclosure process
