CVE-2026-28466

Description

### Summary A remote code execution (RCE) vulnerability in the gateway-to-node invocation path allowed an authenticated gateway client to bypass node-host exec approvals by injecting internal control fields into `node.invoke` parameters. ### Affected Component - Gateway method: `node.invoke` for node command `system.run` - Node host runner: exec approval gating for `system.run` ### Impact If an attacker can authenticate to a gateway (for example via a leaked/shared gateway token or a paired device token with `operator.write`), they could execute arbitrary commands on connected node hosts that support `system.run`. This can lead to full compromise of developer workstations, CI runners, and servers running the node host. ### Technical Details The gateway forwarded user-controlled `params` to node hosts without sanitizing internal approval fields. The node host treated `params.approved === true` and/or `params.approvalDecision` as sufficient to skip the approval workflow. ### Fix Patched in **OpenClaw `2026.2.14`**. - Commits: - `318379cdb8d045da0009b0051bd0e712e5c65e2d` - `a7af646fdab124a7536998db6bd6ad567d2b06b0` - `c1594627421f95b6bc4ad7c606657dc75b5ad0ce` - `0af76f5f0e93540efbdf054895216c398692afcd` - Gateway strips untrusted approval control fields from `system.run` user input. - Gateway only re-attaches approval flags when `params.runId` references a valid `exec.approval.request` record and the request context matches. Approval IDs are bound to the requesting device identity (stable across reconnects), preventing replay by other clients. - Gateway forwards only an allowlisted set of `system.run` parameters, preventing future control-field smuggling. ### Mitigations - Upgrade to `2026.2.14` or later. - Restrict access to the gateway (do not expose it to untrusted networks/users). - Rotate gateway credentials if you suspect token/password exposure. - Disable remote command execution on nodes by blocking `system.run` at the gateway (`gateway.nodes.denyCommands`) and/or by configuring node exec security to `deny`. ### Credits OpenClaw thanks @222n5 for reporting this issue.
