Wanwu before 0.6.3 contains an insecure direct object reference vulnerability that allows any authenticated enabled user to delete other users' legacy AppKeys by supplying a numeric apiId. Attackers can iterate sequential key IDs against DELETE /v1/appspace/app/key to revoke AppKeys across organizations, breaking MCP and OpenAPI clients until owners issue new keys.
