Authorization Header Exposure in OpenClaw via MCP SSE Redirects

Publication date: 2026-07-17

Last updated on: 2026-07-17

Assigner: VulnCheck

Description
OpenClaw before 2026.6.5 could forward Authorization headers during MCP SSE redirects. When the affected feature is enabled and reachable, a lower-trust caller or configured input path could execute or persist actions beyond the caller's intended authorization. Impact depends on the operator's configuration and whether lower-trust input can reach the affected path.

Executive Summary

OpenClaw before version 2026.6.5 has a flaw where Authorization headers are forwarded during MCP SSE redirects. This allows lower-trust callers or input paths to execute or persist actions beyond their intended authorization scope. The impact depends on the operator's configuration and whether lower-trust input can reach the affected path.

Detection Guidance

To detect this vulnerability, check if your OpenClaw instance is running a version prior to 2026.6.5. Verify the MCP SSE redirects feature is enabled and accessible by lower-trust paths. Monitor network traffic for unexpected Authorization header forwarding during SSE interactions.

Impact Analysis

An attacker with network access and low privileges could exploit this to forward Authorization headers, potentially gaining unauthorized access to sensitive actions or data. The impact varies based on the operator's setup and whether the affected feature is exposed to untrusted input.

Compliance Impact

This vulnerability could lead to unauthorized exposure of sensitive data, potentially violating GDPR (data protection) and HIPAA (health information privacy) requirements. Unauthorized access to credentials or actions may result in non-compliance with these regulations.

Mitigation Strategies

Immediately upgrade OpenClaw to version 2026.6.5 or later. If upgrading is not possible, disable the MCP SSE redirects feature or restrict access to trusted operators only. Ensure no lower-trust input paths can reach the affected feature.
