Received Received - Intake

Race Condition in OpenClaw MS Teams Integration

Publication date: 2026-07-17

Last updated on: 2026-07-17

Assigner: VulnCheck

Description
OpenClaw before 2026.5.28 contains a race condition in the MS Teams safeFetch DNS rebinding check. When the affected feature is enabled and reachable, a lower-trust caller or configured input path could win a timing window between the DNS validation check and use, allowing actions that should have required a stronger authorization or policy check. Practical impact depends on the operator's configuration and whether lower-trust input can reach that path.

Executive Summary

OpenClaw before version 2026.5.28 has a race condition in the MS Teams safeFetch DNS rebinding check. This means there is a timing issue where a lower-trust caller or input path could exploit a gap between DNS validation and actual use, potentially bypassing stronger authorization checks. The vulnerability is specific to the safeFetch feature and depends on the operator's configuration.

Detection Guidance

Detecting this vulnerability requires checking if OpenClaw versions before 2026.5.28 are installed and if the MS Teams safeFetch feature is enabled. Review OpenClaw logs for DNS rebinding checks and timing inconsistencies. Check for unauthorized actions performed by lower-trust callers during the timing window.

Impact Analysis

The impact depends on your OpenClaw configuration and whether lower-trust input can reach the affected path. If exploitable, it could allow unauthorized actions that should require stronger authorization, potentially leading to data access or policy violations. Practical impact varies based on setup.

Compliance Impact

This vulnerability could potentially impact compliance with GDPR or HIPAA if it allows unauthorized access to personal or health data through the race condition in MS Teams safeFetch. The flaw may bypass authorization checks, increasing risk of data exposure or unauthorized actions depending on operator configuration and data handling.

Mitigation Strategies

Upgrade OpenClaw to version 2026.5.28 or later. Disable the MS Teams safeFetch feature if not required. Restrict access to the affected feature to trusted operators only. Monitor network traffic for unusual DNS rebinding attempts or unauthorized actions.
