OpenClaw: Plugin subagent routes could bypass gateway authorization with synthetic admin scopes

Critical severity GitHub Reviewed Published Mar 12, 2026 in openclaw/openclaw • Updated Mar 13, 2026

Package

npm openclaw (npm)

Affected versions

>= 2026.3.7, < 2026.3.11

Patched versions

2026.3.11

Description

Summary

In affected versions of openclaw, the plugin subagent runtime dispatched gateway methods through a synthetic operator client that always carried broad administrative scopes. Plugin-owned HTTP routes using auth: "plugin" could therefore trigger admin-only gateway actions without normal gateway authorization.

Impact

This is a critical authorization bypass. An external unauthenticated request to a plugin-owned route could reach privileged subagent runtime methods and perform admin-only gateway actions such as deleting sessions, reading session data, or triggering agent execution.

Affected Packages and Versions

  • Package: openclaw (npm)
  • Affected versions: >= 2026.3.7, < 2026.3.11
  • Fixed in: 2026.3.11

Technical Details

The new plugin subagent runtime preserved neither the original caller's auth context nor least-privilege scope. Instead, it executed gateway dispatches through a fabricated operator client with administrative scopes, which was reachable from plugin-owned routes that intentionally bypass normal gateway auth so plugins can perform their own webhook verification.

Fix

OpenClaw now preserves real authorization boundaries for plugin subagent calls instead of dispatching them through synthetic admin scopes. The fix shipped in openclaw@2026.3.11.

Workarounds

Upgrade to 2026.3.11 or later.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.

Weaknesses

Improper Privilege Management

The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. Learn more on MITRE.

Improper Authorization

The product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action. Learn more on MITRE.
