CVE-2026-100596

HIGH8.8

Published 2026-09-26 · Source disclosure@vulncheck.com

Description

OpenClaw versions before 2026.7.1 fail to properly authorize non-owner users executing MCP configuration changes through /mcp set and /mcp unset commands. Attackers can persist arbitrary stdio MCP commands that execute with OpenClaw process privileges when configuration loads, compromising host confidentiality, integrity, and availability.

CVE-2026-100599
OpenClaw versions 2026.5.1 through 2026.7.0 fail to apply the configured exec approval path to Google Meet node commands. The googlemeet.chrome command accepts caller-supplied audio command arrays and executes them on a paired node without going through the normal system.run approval flow. In deployments with the Google Meet plugin enabled, a paired Chrome node, and the googlemeet.chrome node command allowed, a tool-enabled agent able to invoke that command can execute attacker-selected processes on the paired node, impacting files, credentials, browser profiles, and availability on that node. The issue is fixed in 2026.7.1; as a workaround, remove googlemeet.chrome from allowed node commands or disable the Google Meet plugin.

CVE-2026-100598
OpenClaw (npm package openclaw) before 2026.7.1 incorrectly binds Signal approval reactions. In affected versions, a reaction intended to resolve a structured approval request could instead attach to ordinary outbound text when unrelated outbound messages and a pending approval are present in the same conversation. As a result, an approver's reaction to unrelated text could be interpreted as approving or denying a pending host action; the practical impact depends on the pending request, conversation timing, and the actions available to the OpenClaw process. The issue does not change the authority of correctly identified approvers. This is fixed in version 2026.7.1.

CVE-2026-100597
OpenClaw (npm package 'openclaw') before 2026.7.1 is vulnerable to a time-of-check time-of-use race condition in OpenShell local mirror filesystem mutation operations. The remove, mkdir, and rename operations could act on a different filesystem target after OpenClaw completed its sandbox path-safety check, if the path is changed concurrently. An attacker able to win the race can cause a sandboxed operation to delete, create, or rename a host path outside the intended mirror root with the permissions of the OpenClaw process user. This does not require an operator to have granted host filesystem access outside the sandbox. The issue is fixed in 2026.7.1.

CVE-2026-100589
OpenClaw versions before 2026.7.1 contain a sandbox bypass vulnerability in the browser tool that allows sandboxed sessions to access paired node browser actions despite allowHostControl=false configuration. Attackers with control over sandboxed agent input can select a paired node and perform host browser operations, inspecting or manipulating the connected browser profile and its authenticated state.

CVE-2026-100588
OpenClaw (npm package 'openclaw') before 2026.7.1 does not enforce the administrator scope requirement on browser control when it is reached through the node.invoke method, although direct browser.request access requires administrator scope. In Gateway deployments that honor caller identity and narrower operator scopes, a write-scoped caller with access to a connected browser-capable node can inspect pages, navigate tabs, or interact with browser-visible applications without the configured admin requirement; practical impact depends on the browser profile and signed-in state. Shared-secret token and password callers are considered fully trusted operators under OpenClaw's security model and are not affected. The issue is fixed in 2026.7.1.
