NVD description
OpenClaw before 2026.9.4 contains an incorrect authorization vulnerability in the mcp.app.view method that allows read-scoped operators to execute MCP App tools requiring operator.write scope. Attackers with operator.read tokens can obtain a standalone ticket from mcp.app.view and redeem it at the MCP app view endpoint to invoke state-changing tools without proper authorization checks.
What to do
- Upgrade OpenClaw to
2026.9.4or later. - Do not expose the component's API or UI to the internet without authentication in front of it.
