CVE-2026-62227 in OpenClaw
Summary
by MITRE • 07/17/2026
OpenClaw 2026.4.14 before 2026.5.26 contain a server-side request forgery vulnerability in browser snapshot routes that fail to validate post-navigation destinations. Attackers with lower-trust access can bypass OpenClaw policy checks to reach network destinations that should have been blocked.

The vulnerability identified in OpenClaw versions prior to 2026.5.26 represents a critical server-side request forgery flaw that undermines the application's security controls through improper validation of post-navigation destinations within browser snapshot routes. This issue manifests when the system fails to adequately validate or sanitize user-provided URLs or destination parameters that are processed after navigation events, creating an avenue for unauthorized access to internal network resources that should remain protected by policy enforcement mechanisms.
The technical implementation of this vulnerability stems from insufficient input validation and sanitization practices within the browser snapshot functionality, where the application accepts potentially malicious destination URLs without proper verification against established security policies. This weakness allows attackers with lower privilege levels to manipulate navigation parameters in ways that bypass existing access controls, effectively enabling them to traverse network boundaries that would normally be restricted. The flaw operates at the application layer and specifically targets the routing mechanisms responsible for handling browser snapshot operations, making it particularly dangerous as it can be exploited through legitimate user interfaces without requiring elevated privileges.
From an operational impact perspective, this vulnerability creates significant risk exposure for organizations relying on OpenClaw for network security monitoring and access control enforcement. Attackers can leverage this weakness to access internal systems, services, or data that should remain isolated from external or lower-privileged users, potentially leading to data exfiltration, lateral movement within networks, or further exploitation of compromised systems. The vulnerability's severity is amplified by its ability to bypass existing policy checks, meaning that even well-configured security controls may be rendered ineffective against this specific attack vector.
The root cause of this vulnerability aligns with common weakness patterns identified in the CWE database under CWE-918, which addresses server-side request forgery vulnerabilities. This classification specifically covers situations where applications fail to validate or sanitize URLs that are used to make requests to other systems, particularly when those URLs originate from user-controlled input. From an adversarial perspective, this vulnerability maps directly to ATT&CK technique T1071.004, which involves application layer protocol tunneling, as attackers can leverage the snapshot functionality to establish unauthorized connections through the application's legitimate interfaces.
Organizations should implement immediate mitigations including comprehensive input validation and sanitization of all navigation parameters within browser snapshot routes, implementing strict destination whitelisting or blacklisting mechanisms, and enforcing robust policy enforcement controls that cannot be bypassed through parameter manipulation. Additionally, network segmentation and monitoring should be enhanced to detect unauthorized access patterns that might indicate exploitation attempts. The recommended long-term solution involves upgrading to OpenClaw version 2026.5.26 or later, which includes proper validation mechanisms for post-navigation destinations and enhanced policy enforcement controls that prevent bypass of security restrictions through manipulated request parameters.
