GHSA-c28g-vh7m-fm7v: 
OpenClaw (formerly Moltbot or Clawdbot) vulnerability analysis and mitigation

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.
