CVE-2026-100595 in OpenClaw
Summary
by MITRE • 09/26/2026
OpenClaw versions before 2026.7.1 contain an authorization bypass vulnerability in the diagnostics export command that allows non-owner channel senders to access owner-only host diagnostic bundles. Attackers can request and receive diagnostic details about the host, configuration, runtime, and connected services intended only for owners.

The identified security flaw resides within OpenClaw versions prior to 2026.7.1, specifically affecting the diagnostics export command functionality. This vulnerability represents a critical failure in access control mechanisms, allowing unauthorized users to bypass authorization checks that are designed to restrict sensitive system information to channel owners only. The core technical issue stems from an improper validation of user privileges when processing requests for diagnostic data exports. Instead of verifying whether the requesting entity holds the necessary owner-level permissions before generating or transmitting the bundle, the application processes the request based on insufficient criteria, effectively treating non-owner senders with the same level of trust as authorized administrators. This misconfiguration enables any authenticated user who can interact with the diagnostics export feature to retrieve comprehensive host diagnostic bundles that contain sensitive operational data.
The impact of this vulnerability is significant due to the nature and depth of information exposed through these diagnostic bundles. These files typically aggregate detailed insights into the host environment, including system configuration parameters, runtime states, memory usage patterns, network connectivity details, and status reports for connected services. For an attacker, gaining access to this data facilitates extensive reconnaissance activities that can lead to further exploitation within the infrastructure. By analyzing the exposed configuration and runtime information, adversaries can identify potential weaknesses in service deployments, discover internal IP addresses or domain names, understand software versions running on critical components, and map out the attack surface of the organization's environment. This level of visibility is typically reserved for system administrators who require such data for maintenance and troubleshooting purposes, making its unauthorized disclosure a severe breach of confidentiality principles.
From a classification perspective, this vulnerability aligns with CWE-269, which denotes Improper Privilege Assignment, as the application fails to enforce appropriate access controls on privileged operations. Furthermore, it corresponds to CWE-862, Missing Authorization, because the system does not verify that the user has the necessary permissions for the specific action being performed. In terms of offensive security frameworks such as MITRE ATT&CK, this flaw supports techniques related to Discovery and Collection, specifically allowing attackers to gather information about the target environment without triggering typical alerts associated with direct exploitation attempts. The ability to extract diagnostic data remotely makes it a valuable tool for initial access phase reconnaissance, potentially leading to lateral movement or privilege escalation if additional vulnerabilities are discovered within the exposed configuration details.
To mitigate this risk, organizations running OpenClaw versions before 2026.7.1 must apply the vendor-provided patch immediately upon availability. The update addresses the authorization bypass by implementing strict role-based access control checks on the diagnostics export endpoint, ensuring that only users with explicit owner privileges can request and receive these sensitive bundles. In environments where immediate patching is not feasible due to operational constraints, temporary mitigations should include restricting network-level access to the OpenClaw interface for non-essential personnel, enforcing multi-factor authentication for all administrative functions, and monitoring logs for unusual patterns of diagnostic export requests from standard user accounts. Additionally, implementing web application firewalls with rules that detect and block anomalous API calls related to privilege escalation can provide an additional layer of defense against exploitation attempts while the underlying code vulnerability remains unpatched.
