## Technical details

An authorization bypass in the POST /v1/appspace/app/key endpoint fails to verify that an authenticated user owns the MCP server UUID they specify when minting an AppKey. An attacker with valid authentication can submit a victim's MCP server UUID with appType "mcpserver" to create a key, then use it to open sessions and invoke the server's tools with the victim's upstream authentication credentials.
