Ground-truth vulnerability-hunting benchmarks: challenge definitions with known-vulnerable targets, ground-truth vulnerability records with match keywords and point values, precision/recall/F1 scoring of discovered findings against ground truth, time-to-finding metrics, decoy clean samples to measure false-positive rates, and severity breakdown reporting. Use when evaluating how well an agent or tool finds real vulnerabilities, building a vulnerability-hunting eval set, or scoring a…
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
# CVE-Hunt Benchmark Harness
Derived from T3MP3ST's `src/benchmark/index.ts` and `bench/` corpora
(Apache-2.0). The point of a ground-truth benchmark: measure finding quality —
precision AND recall — instead of counting scanner output.
## 1. Challenge definition
A benchmark challenge bundles everything needed to score a hunt:
```
id, name, description, difficulty(easy|medium|hard|expert),
target{address, type, zone},
tasks[{name, description, phase, operatorType, priority}],
groundTruth[{id, title, severity, category, matchKeywords[], points}],
timeLimitSec
```
- `groundTruth` is the answer key: every KNOWN vulnerability in the target with
its severity, category, `matchKeywords` (what a correct finding should
mention), and a `points` value.
- `tasks` defines the hunting workflow phases so runs are comparable.
- `timeLimitSec` bounds the run — time-to-finding is a scored metric.
## 2. Scoring — precision, recall, F1
For a run that produced `findings[]` against `groundTruth[]`:
- A finding matches a ground-truth vuln when it hits the vuln's `matchKeywords`
(keyword containment over the finding's title/description/category).

How to install
mdr add miosa-osa/osa/cve-hunt-benchmark-harness@sha256:d1d19dae2b47ace2The line at the top of this page pins the label git:20260913.e13b6b8, 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.
