Summary

OpenClaw: Owner-enforced commands could accept wildcard channel senders as command owners

Details

Impact

OpenClaw deployments before 2026.4.21 could treat a non-owner sender as authorized for owner-enforced slash commands when all of the following were true:

a channel plugin declared commands.enforceOwnerForCommands: true;
the channel accepted wildcard inbound senders with allowFrom: ["*"];
no explicit commands.ownerAllowFrom was configured.

In that state, src/auto-reply/command-auth.ts reused the channel inbound wildcard as part of the command-owner decision. A sender who was not the owner could therefore pass the owner-command gate for commands such as /send, /config, or /debug on the affected channel.

The issue is limited to the command-owner authorization axis. It does not by itself grant owner-only tool access, host/sandbox access, or gateway administrator scope.

Affected Packages / Versions

Package: openclaw on npm
Affected versions: <= 2026.4.20
Patched version: 2026.4.21

The latest public release, 2026.4.21, contains the fix.

Patches

The fix requires a concrete owner identity or internal operator-admin scope when a plugin enforces owner-only commands. Wildcard channel allowFrom no longer implies wildcard command ownership.

Fix commits:

2aa93d44a1b2c7058c371f261fda2b5d4de4a882 on main
995febb7b1e811ff6a1df5b18c22de94103f4c9f in the 2026.4.21 release line

Workarounds

Upgrade to openclaw@2026.4.21 or later. Before upgrading, avoid wildcard/open-DM sender policy on owner-enforced channels, or configure commands.ownerAllowFrom to the intended owner identities.

Vulnerability from cvelistv5 – Published: 2026-05-11 16:46 – Updated: 2026-05-11 17:26 X_Open Source

Title

OpenClaw < 2026.4.21 - Authorization Bypass in Owner-Enforced Commands via Wildcard Channel Senders

Summary

OpenClaw before 2026.4.21 contains an authorization bypass vulnerability in command-auth.ts that allows non-owner senders to execute owner-enforced slash commands when wildcard inbound senders are configured without explicit owner allowFrom settings. Attackers can exploit this by sending commands like /send, /config, or /debug on affected channels to bypass owner-only command authorization checks.
