CVE-2026-62206: Openclaw Auth Bypass Vulnerability

CVE-2026-62206 Overview

CVE-2026-62206 is a missing authorization vulnerability [CWE-862] affecting OpenClaw versions before 2026.6.9. The flaw resides in the Discord moderation action path, where a lower-trust caller or configured input path can invoke moderation actions that should require stronger authorization or policy checks. The vulnerability is network-reachable and requires low privileges, but exploitation depends on operator configuration and whether attacker-controlled input can reach the affected code path. The GitHub Security Advisory GHSA-f6p7-6326-vf7v and VulnCheck advisory describe the issue as an authentication bypass via moderation actions.

Critical Impact
Lower-trust callers can execute Discord moderation actions without the intended authorization checks, enabling unauthorized state changes to communities using vulnerable OpenClaw deployments.

Affected Products

OpenClaw versions before 2026.6.9
Node.js-based OpenClaw deployments (cpe:2.3:a:openclaw:openclaw:*:*:*:*:*:node.js:*:*)
Discord bot instances running affected OpenClaw builds

Technical Details for CVE-2026-62206

Vulnerability Analysis

OpenClaw exposes Discord moderation actions through code paths that fail to enforce consistent authorization checks. The advisory classifies the weakness as [CWE-862] Missing Authorization, meaning the application performs sensitive actions without verifying that the caller holds the required permissions or role. Moderation actions in a Discord context typically include kicks, bans, message deletions, role changes, and channel restrictions.

Because the check is missing rather than incorrectly implemented, a caller who reaches the vulnerable path can trigger moderation actions even when policy would ordinarily block them. The advisory notes that practical impact depends on the operator's configuration and whether lower-trust input can reach the affected path. Deployments that expose OpenClaw commands to broader user groups or accept externally-sourced input carry higher risk.

Root Cause

The root cause is the absence of a stronger authorization or policy check before executing moderation actions in versions prior to 2026.6.9. The action handler proceeds to modify Discord server state without verifying the caller's trust level against the sensitivity of the action.

Attack Vector

The attack vector is network-based with low attacker privileges required and no user interaction. An attacker who can send commands to a vulnerable OpenClaw instance, either directly through Discord or through a configured input path, can invoke moderation actions that should be gated by stronger checks. Refer to the GitHub Security Advisory for the technical description.

Detection Methods for CVE-2026-62206

Indicators of Compromise

Discord audit log entries showing moderation actions (bans, kicks, role changes, message deletions) attributed to the OpenClaw bot but not initiated by authorized moderators.
Unexpected role reassignments or channel permission changes correlated with OpenClaw command invocations from low-privilege users.
Command invocations from user IDs that fall outside the operator's configured moderator allowlist.

Detection Strategies

Inventory all OpenClaw instances and identify any running versions earlier than 2026.6.9.
Correlate Discord audit logs with OpenClaw command logs to identify moderation actions triggered by callers who should not have that authority.
Review any input paths (webhooks, integrations, forwarded commands) that reach OpenClaw moderation handlers to determine whether lower-trust sources can reach them.

Monitoring Recommendations

Forward Discord audit logs and OpenClaw application logs to a centralized logging or SIEM platform for continuous review.
Alert on bursts of moderation actions from a single caller or within a short time window.
Track version metadata for deployed OpenClaw instances and alert on any instance running a version below 2026.6.9.

How to Mitigate CVE-2026-62206

Immediate Actions Required

Upgrade OpenClaw to version 2026.6.9 or later on all deployments.
Audit Discord servers using OpenClaw for unauthorized moderation actions performed since the vulnerable version was deployed.
Restrict which users and input paths can invoke OpenClaw commands until the upgrade is verified.

Patch Information

The maintainers released a fix in OpenClaw 2026.6.9. Deployment instructions and the full technical writeup are available in the GitHub Security Advisory GHSA-f6p7-6326-vf7v and the VulnCheck advisory. Operators using package managers should update the openclaw dependency and redeploy the bot process.

Workarounds

Disable or restrict Discord moderation commands exposed by OpenClaw until the patched version is deployed.
Limit OpenClaw command access to a narrow, trusted moderator role using Discord's native permission model.
Remove or firewall any auxiliary input paths (webhooks, external integrations) that could deliver commands to the moderation handler.

bash

# Upgrade OpenClaw to the fixed version
npm install openclaw@2026.6.9
npm ls openclaw
