Connect response values to later request parameters and keep expanding the attack graph after each finding.
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
# Data Linkage ## Goal 把“一个响应里出现的值”变成“另一个接口的输入”，持续扩大攻击面。 ## Tools / Inputs - `_endpoint_params.json` - `_leaked_values.json` - Response mining、PairingEngine、method fallback - 资源索引：`references/INDEX.md`；候选资源：`response-chaining.md`、`discovery-amplification.md` ## Constraints 1. 每个有意义响应都要提取字段和值。 2. 高价值值优先：token、ID、key、role、org、tenant、email、phone。 3. 每次值池增长后重新检查可注入接口。 4. 已消费/未消费状态必须记录。 5. 不把单次命中当终点；命中后继续看它打开了什么新门。 ## Chain Questions - 这个值能喂给哪些参数名相同或语义相近的接口？ - 它能否扩大查询范围、越权范围或角色权限？ - 新响应是否产生了新的 token、ID、key 或路径？ - 三轮无新增价值后是否该换方向？

How to install
mdr add hellodqy/mastermind-bug-bounty/data-linkage@sha256:007837734a130e74The line at the top of this page pins the label git:20260709.c284c01, 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.
