Frequently Asked Questions
What is GHSA-9c3v-684m-579c?
### 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.
Is GHSA-9c3v-684m-579c actively exploited?
No confirmed active exploitation of GHSA-9c3v-684m-579c has been reported, but organizations should still patch proactively.
How to fix GHSA-9c3v-684m-579c?
Update to patched version: OpenClaw 2026.6.5.
What is the CVSS score for GHSA-9c3v-684m-579c?
GHSA-9c3v-684m-579c has a CVSS v3.1 base score of 6.5 (MEDIUM).

CWE-200 — Exposure of Sensitive Information to an Unauthorized Actor: The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
- [Architecture and Design] Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
