CVE-2026-62219 in OpenClaw
Summary
by MITRE • 07/17/2026
OpenClaw 2026.2.12 before 2026.5.26 contain an authorization bypass vulnerability in the hooks allowedAgentIds validation. A lower-trust caller or configured input path can bypass agent ID restrictions by submitting blank agent IDs, allowing actions that should require stronger authorization or policy checks.

The OpenClaw software version 2026.2.12 through 2026.5.25 contains a critical authorization bypass vulnerability that stems from insufficient validation of agent identifiers within the hooks system. This flaw resides in the allowedAgentIds validation mechanism, which is designed to enforce strict access controls based on agent identification. The vulnerability manifests when a lower-privilege caller or an attacker with access to configured input paths submits blank or empty agent IDs as part of the validation process, effectively circumventing the intended authorization checks that should prevent unauthorized actions.
The technical implementation of this vulnerability involves a failure in input sanitization and validation logic within the hooks subsystem. When the system processes incoming requests containing agent identifiers, it does not properly validate whether blank values are legitimate or represent an attempt to bypass security controls. This weakness allows malicious actors to exploit the system by submitting empty agent ID fields, which the validation routine accepts as valid inputs rather than rejecting them as invalid. The flaw operates at the application level and represents a classic case of insufficient authorization checking that directly violates fundamental security principles.
This authorization bypass vulnerability carries significant operational impact across multiple attack vectors and threat scenarios. An attacker exploiting this weakness could perform actions that require higher privilege levels or specific policy compliance without proper authorization, potentially leading to unauthorized system modifications, data access violations, or privilege escalation within the OpenClaw environment. The vulnerability is particularly concerning because it allows bypass of agent ID restrictions, which are typically implemented as a core security control mechanism for managing trust boundaries and access permissions.
The vulnerability maps directly to CWE-285, which addresses insufficient authorization in software systems, and aligns with ATT&CK technique T1078.004 related to valid accounts and privilege escalation. Organizations utilizing OpenClaw versions within the affected range face potential exposure to attackers who can manipulate the hooks validation logic through crafted input paths. The impact extends beyond immediate unauthorized actions to include potential data integrity compromises, access control bypasses, and possible lateral movement opportunities within systems that rely on OpenClaw for automated operations.
The recommended mitigation strategy involves implementing robust input validation that explicitly rejects blank or empty agent ID values during the hooks validation process. Security patches should enforce strict validation rules that ensure all agent identifiers contain legitimate values before permitting any authorized actions to proceed. Organizations should also consider implementing additional monitoring and logging mechanisms around hook execution points to detect anomalous patterns of blank agent ID submissions. Furthermore, access controls should be reviewed and strengthened through principle of least privilege enforcement, ensuring that even if bypass attempts succeed, the scope of potential damage remains limited. System administrators should immediately upgrade to OpenClaw version 2026.5.26 or later, which contains the patched validation logic, and conduct thorough security assessments of all systems utilizing the affected software components.
