How to Audit and Patch OpenClaw Feishu Auth CVEs (CVE-2026-62187/62188)

Two high-severity CVEs affecting OpenClaw’s Feishu integration were publicly disclosed on July 28, 2026 as part of a broader July 2026 security advisory wave. If you use the @openclaw/feishu integration and haven’t upgraded recently, this is a patch-now situation.

Here’s what’s affected, what the fix looks like, and what else to check if you’re auditing your OpenClaw security posture this week.

The Vulnerabilities at a Glance

CWE-863 is “Incorrect Authorization” — the vulnerability class where a system performs authorization checks but does so incorrectly, allowing lower-trust callers to perform actions that should require higher-privilege authentication.

In this case: lower-trust callers can bypass per-account disablement in the Feishu integration and perform actions that require stronger authorization than they possess. The GitHub Security Advisory (GHSA-2q7j-2vhx-56g8) title is “Feishu tools could ignore per-account disablement.”

The CVSS 8.1 score reflects high impact on both confidentiality and integrity, with a network attack vector — meaning this is exploitable remotely, not just via local access.

Step 1: Check Your Installed Version

First, determine which version of @openclaw/feishu you have installed:

npm list @openclaw/feishu

Or check your package.json or package-lock.json for the installed version. If you see any version at or below 2026.6.6, you are affected and should upgrade immediately.

You can also check the globally installed OpenClaw version:

openclaw --version

Note: The patch for these CVEs was released in @openclaw/feishu v2026.6.9. The OpenClaw core package versioning may differ — check the @openclaw/feishu package specifically if you have it installed separately. Verify version details against the GitHub Security Advisory GHSA-2q7j-2vhx-56g8 and NVD entry for CVE-2026-62187.

Step 2: Upgrade to v2026.6.9 or Later

If you’re on an affected version, upgrade the package:

npm install @openclaw/feishu@latest

Or specify the patched version explicitly:

npm install @openclaw/[email protected]

After upgrading, verify the installed version:

npm list @openclaw/feishu

Restart your OpenClaw gateway after upgrading to ensure the patched code is active:

openclaw gateway restart

Step 3: Audit Your Feishu Integration Configuration

Beyond patching the vulnerability, take this opportunity to review your Feishu integration settings:

Review which accounts are enabled/disabled. The vulnerability allowed disabled account restrictions to be bypassed — verify that your per-account disablement settings are correct and that no unexpected accounts were active.

Audit recent Feishu activity logs. If you were running an affected version, review recent Feishu integration activity for unexpected actions. Check your OpenClaw activity logs for operations that shouldn’t have been possible given your access configuration.

Review the Feishu integration scope. Does the integration have access to more Feishu spaces, channels, or capabilities than it needs? Apply least-privilege principles to the integration’s permissions.

Step 4: Check the Full July 2026 OpenClaw CVE Wave

The Feishu CVEs are part of a broader July 2026 OpenClaw security advisory release. The same wave included:

• CVE-2026-62213 / CVE-2026-62214 — Microsoft Teams token leakage (CVSS 8.8, higher severity than the Feishu CVEs)
• Additional device pairing bypass CVEs

If you use OpenClaw’s Microsoft Teams integration, the Teams token leakage CVEs are actually rated more severely (CVSS 8.8). Review those advisories on GitHub Security Advisories and patch accordingly.

Recommended: Check the full list of July 2026 OpenClaw security advisories at github.com/openclaw/openclaw/security/advisories to ensure you have a complete picture of your exposure.

Step 5: Pin to a Known-Good Version

Given the July 2026 advisory wave, and separately, the OpenClaw Foundation’s acknowledgment of stability issues in the v2026.7.x series (see our related coverage), now is a good time to pin your production OpenClaw deployment to a known-good version.

The OpenClaw Foundation has pointed to the v2026.6.x extended-stable channel as the recommended production target. The v2026.6.9 patch that fixes these CVEs falls within that channel. Locking your npm dependency to a specific patch version in your package.json prevents unexpected upgrades:

{
  "dependencies": {
    "@openclaw/feishu": "2026.6.9"
  }
}

Or use a tilde range if you want to pick up patch-level fixes within the same minor version:

{
  "dependencies": {
    "@openclaw/feishu": "~2026.6.9"
  }
}

What the CVSS 8.1 Score Means in Practice

A CVSS base score of 8.1 (High) reflects:

• Network-exploitable — no physical access needed
• Low complexity — the attack doesn’t require special conditions
• High impact on confidentiality and integrity — a successful exploit can expose data or cause unauthorized modifications

In an OpenClaw deployment context, a Feishu authorization bypass could allow a lower-privilege AI agent to perform Feishu actions (send messages, read channels, access workspaces) as if it had higher-trust account permissions. For organizations using OpenClaw with Feishu for internal communications, this is a meaningful exposure.

Summary Checklist

• Run npm list @openclaw/feishu — confirm version is 2026.6.9 or later
• Upgrade if needed: npm install @openclaw/[email protected]
• Restart OpenClaw gateway after upgrading
• Review Feishu integration access configuration and recent activity logs
• Check GitHub Security Advisories for CVE-2026-62213/62214 (Teams token leakage, CVSS 8.8)
• Consider pinning to v2026.6.x extended-stable channel in production
