Explore WebSocket state, authentication, subscriptions, and replay as chained attack surfaces.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# WebSocket Test ## Goal 判断 WebSocket 是否在握手、消息、订阅、重放或 Origin 校验中暴露越权能力。 ## Tools / Inputs - WS/WSS URL、Socket.IO/STOMP hints、tokens、room/channel/user IDs - 资源索引：`references/INDEX.md`；候选资源：`websocket-security-testing.md`；跨协议链路再读 `decision-trees.md` ## Constraints 1. 不做连接耗尽或破坏性 DoS。 2. 用测试账号验证跨用户订阅或消息动作。 3. 每条消息都关注 userId、roomId、tenantId、role 等可控字段。 4. 成功后证明实际接收或执行了不该发生的事件。 5. 新 ID/channel/token 回写值池。 ## Chain Questions - 认证发生在握手还是消息体？ - 换 token 或 userId 后订阅边界是否变化？ - 消息是否可重放、篡改或跨房间发送？ - WS 泄露的数据能否反哺 HTTP API？

How to install
mdr add hellodqy/mastermind-bug-bounty/websocket-test@sha256:4e1e7717cfcfd037The line at the top of this page pins the label git:20260914.819e838, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
