Vulnerability from github – Published: 2026-02-17 21:39 – Updated: 2026-03-06 01:02

Summary

OpenClaw authorization bypass: operator.write can resolve exec approvals via chat.send -> /approve

Details

Summary

What this means (plain language)

If you give a client “chat/write” access to the gateway (operator.write) but you do not intend to let that client approve exec requests (operator.approvals), affected versions could still let that client approve/deny a pending exec approval by sending the /approve chat command.

This is mainly relevant for shared or multi-client setups where different tokens are intentionally scoped differently. Single-operator installs are typically less impacted.

Technical summary

A gateway client authenticated with a device token scoped only to operator.write (without operator.approvals) could approve/deny pending exec approval requests by sending a chat message containing the built-in /approve command.

exec.approval.resolve is correctly scoped to operator.approvals for direct RPC calls, but the /approve command path invoked it via an internal privileged gateway client.

Affected Packages / Versions

openclaw (npm): < 2026.2.2

Fix

Fixed in openclaw 2026.2.2.
Fix commit(s): efe2a464afcff55bb5a95b959e6bd9ec0fef086e.
Change: when /approve is invoked from gateway clients (webchat/internal channel), it now requires the requesting client to have operator.approvals (or operator.admin).

Workarounds

Upgrade to openclaw >= 2026.2.2.
If you cannot upgrade: avoid issuing write-only device tokens to untrusted clients; disable text commands (commands.text=false) or restrict access to the webchat/control UI.

CVE-2026-28473 (GCVE-0-2026-28473)

Vulnerability from cvelistv5 – Published: 2026-03-05 21:59 – Updated: 2026-03-09 18:06

Title

OpenClaw < 2026.2.2 - Authorization Bypass via /approve Chat Command

Summary

OpenClaw versions prior to 2026.2.2 contain an authorization bypass vulnerability where clients with operator.write scope can approve or deny exec approval requests by sending the /approve chat command. The /approve command path invokes exec.approval.resolve through an internal privileged gateway client, bypassing the operator.approvals permission check that protects direct RPC calls.
