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.

OpenClaw MCP SSE redirects could forward Authorization headers
Summary
MCP SSE redirects could forward Authorization headers. In affected versions, a lower-trust caller or configured input path could execute or persist actions beyond the caller's intended authorization.
This advisory is scoped to the named feature and configuration. It does not change OpenClaw's trusted-operator model: authenticated Gateway operators, installed plugins, and intentional local execution surfaces remain trusted unless a separate policy, approval, allowlist, sandbox, or auth boundary is crossed.
Impact
When the affected feature is enabled and reachable, this could execute or persist actions beyond the caller's intended authorization. Practical impact depends on the operator's configuration and whether lower-trust input can reach that path.
Patched Versions
The first stable patched version is 2026.6.5.
Mitigations
Upgrade to a patched OpenClaw release when one is listed. Before upgrading, restrict the affected feature to trusted operators or disable it when it is not needed. As general hardening, keep channel and tool allowlists narrow, avoid sharing one Gateway between mutually untrusted users, and disable the affected feature when it is not needed.
