CVE-2026-53852: OpenClaw Scope Containment Bypass in Device Re-Pairing

Technical summary

CVE-2026-53852 is a scope containment bypass in OpenClaw's device re-pairing mechanism, classified under CWE-636 (Permission Scope Inconsistency). The vulnerability occurs because the re-pairing function does not properly validate or enforce scope boundaries when empty-scope requests are submitted. An authenticated operator can exploit this logic flaw to circumvent containment guards that are designed to limit device access to a specific set of permissions. The attack requires network access and valid authentication credentials but no user interaction, resulting in a CVSS 3.1 base score of 5.4 (Medium severity).

Business impact

The vulnerability poses a moderate insider-threat risk in environments where OpenClaw manages device access and permissions. An authenticated operator—whether a legitimate user with limited scope or a compromised account—can escalate their device access rights beyond what administrators intended, potentially leading to unauthorized viewing or modification of sensitive device data or functions. Organizations relying on OpenClaw's scope-based access control for operational security or compliance segregation should evaluate whether this exposure affects their control baseline.

Affected systems

OpenClaw versions prior to 2026.4.25 are affected. Organizations running OpenClaw should identify all instances in their environment and prioritize patching production deployments that manage sensitive or critical devices.

Exploitability

Exploitation requires valid authentication credentials and network access to the OpenClaw service. No special tools, user interaction, or complex conditions are needed once authenticated. The attack is straightforward to execute, making it a concern for accounts with compromised credentials or for insider threats. The vulnerability is not currently listed on CISA's Known Exploited Vulnerabilities (KEV) catalog, suggesting active exploitation in the wild has not been widely reported at the time of publication.

Remediation

Upgrade OpenClaw to version 2026.4.25 or later. This release includes fixes to the re-pairing request validation logic to properly enforce scope containment. Before patching, review audit logs for any re-pairing requests with empty or anomalous scope parameters that may indicate exploitation attempts.

Patch guidance

Apply OpenClaw version 2026.4.25 or later. Verify the patch through your vendor's official release notes and advisory. Plan patching to minimize operational disruption, particularly for production systems managing critical devices. Consider testing in a non-production environment first to confirm compatibility with your configuration and integrations.

Detection guidance

Monitor OpenClaw logs for re-pairing requests that contain empty scope sets or unusual scope expansion patterns. Alert on any re-pairing operation that grants an operator access to devices outside their previously assigned scope. Correlation with authentication logs can help identify whether these requests originated from unexpected accounts or IP addresses. Check for any historical re-pairing events in the logs prior to patching to identify potential past exploitation.

Why prioritize this

Although the CVSS score is moderate (5.4), the vulnerability enables privilege escalation for authenticated users and directly undermines scope-based access controls. Organizations that rely on OpenClaw for fine-grained device permission management, particularly in sensitive operational environments, should treat this as a near-term patching priority. The relative simplicity of exploitation and the lack of user interaction post-authentication further elevate practical risk.

Risk score, explained

The CVSS 3.1 score of 5.4 reflects a network-accessible, low-complexity attack that requires existing authentication but causes no availability impact and only partial confidentiality and integrity compromise. The score appropriately captures the threat to access control enforcement without overstating the scope. However, organizational risk may be higher if the affected OpenClaw instance manages high-value or compliance-critical devices, warranting context-specific risk assessment.
