CVE-2026-100582 openclaw CVE debrief

Who should care

Defenders responsible for OpenClaw channel plugins, Microsoft Teams, Feishu, Matrix, and Google Chat deployments should assess exposure and prioritize updates to version 2026.8.1 or later. They should also review and restrict channel read permissions for bot accounts to prevent unauthorized access.

Why it matters

Defenders should prioritize updating OpenClaw channel plugins to version 2026.8.1 or later and review channel read permissions for bot accounts to prevent unauthorized access and potential content or metadata exposure.

• Defenders need to verify channel read permissions for bot accounts to prevent unauthorized access.
• Updating OpenClaw channel plugins to version 2026.8.1 or later is crucial to mitigate this vulnerability.
• Restricting channel read permissions can help prevent content or metadata exposure.
• Defenders should review and restrict channel read permissions for bot accounts to prevent unauthorized access.

Technical summary

The OpenClaw channel plugins for Microsoft Teams, Feishu, Matrix, and Google Chat before version 2026.8.1 do not enforce the configured channel read allowlist for caller-supplied explicit read targets in message, reaction, pin, member, and related metadata read actions. This allows a lower-trust sender or a steered agent with access to a channel read action to retrieve content or metadata from channels or rooms excluded by the operator's read policy.

Defensive priority

Defenders should prioritize updating OpenClaw channel plugins to version 2026.8.1 or later to mitigate this vulnerability. They should also review and restrict channel read permissions for bot accounts and ensure that only authorized channels are accessible.

Recommended defensive actions

• Update OpenClaw channel plugins to version 2026.8.1 or later
• Review and restrict channel read permissions for bot accounts
• Ensure that only authorized channels are accessible
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
