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

> CVSS 8.1 authorization bypass vulnerabilities in OpenClaw Feishu integration patched in v2026.6.9. Check your version and upgrade now if running ≤2026.6.6.

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

| CVE | CVSS Score | CWE | Package | Versions Affected | Fixed In |
|-----|-----------|-----|---------|-------------------|----------|
| CVE-2026-62188 | 8.1 (High) | CWE-863 | @openclaw/feishu | ≤2026.6.6 | 2026.6.9 |
| CVE-2026-62187 | 8.1 (High) | CWE-863 | @openclaw/feishu | ≤2026.6.6 | 2026.6.9 |

**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:

```bash
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:

```bash
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](https://github.com/openclaw/openclaw/security/advisories/GHSA-2q7j-2vhx-56g8) and [NVD entry for CVE-2026-62187](https://nvd.nist.gov/vuln/detail/CVE-2026-62187).

## Step 2: Upgrade to v2026.6.9 or Later

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

```bash
npm install @openclaw/feishu@latest
```

Or specify the patched version explicitly:

```bash
npm install @openclaw/feishu@2026.6.9
```

After upgrading, verify the installed version:

```bash
npm list @openclaw/feishu
```

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

```bash
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](https://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:

```json
{
  "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:

```json
{
  "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/feishu@2026.6.9`
- [ ] 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
