}Specifications
| Formats | Docker, JSONL, YAML |
|---|---|
| Delivery | Secure download, Docker Compose, Container registry |
| Cadence | Continuous build; monthly tranches |
| Exploit-and-patch tasks delivered | 16,000 |
| Vulnerability-detection pairs | Tens of thousands, mined from real CVEs |
| Reference tranche | 12 multi-stage containerized targets |
| Each target ships | Vulnerable service, working exploit, patch, checker |
| Grading | Subtask ladder with per-stage machine checks |
| Access | Org-scoped credentials. Exploits and checkers are delivered under a restricted agreement separate from the target images, so evaluation tasks can be withheld from training. |
| Built against | Cybench, CyberSecEval |
What ships
Multi-Stage Exploit Chains
Targets that require a full chain rather than one bug: SQL injection to admin to data export, SSRF to forged JWT to remote execution, XXE, and server-side template injection to RCE.
Non-Web and Cryptographic Targets
Raw-TCP memory corruption and length-extension MAC forgery, so the suite is not purely a web-application benchmark.
Detect-and-Patch Pairs
Vulnerability-detection pairs mined from real CVEs in the CyberSecEval style, each with the defective code, the fix, and a checker that distinguishes them.
Fields
8 fields
| Field | Description |
|---|---|
| target_idstring | Stable identifier for the containerized target. |
| chainstring[] | Ordered exploitation stages the target requires.Example ["injection", "privilege escalation", "data export"] |
| service/directory | The vulnerable service source and its container definition. |
| exploit/directory | A working exploit, retained privately and used to validate the patch. |
| patch/directory | The remediation the defensive variant of the task is graded against. |
| checker/directory | Per-stage machine checks that produce the subtask ladder score. |
| subtasks[]object[] | Ordered rungs with individual pass conditions, enabling partial credit. |

# Bring up one target and score a run docker compose -f targets/<id>/compose.yaml up -d bash harness/score.sh --target <id> --run ./candidate-run # Score is the highest rung reached on the subtask ladder. # Defensive variant re-runs the working exploit against the submitted patch.
Quality checks
3 checksExploit-patch round trip
Whether the shipped patch actually closes the hole the shipped exploit opens.
The exploit is executed against both the patched and unpatched service; the target is rejected unless it fails against the patch and succeeds against the original.
Real measured: passes for every target in the reference tranche.
Stage reachability
Whether each rung of the ladder is independently reachable and independently checkable.
Each subtask checker is exercised against a run that stops at that stage, confirming the ladder scores partial progress rather than collapsing.
Real measured: verified per target before release.
Model difficulty
Where frontier models stop on the ladder.
The shipped calibration harness runs any model against the targets and records the highest rung reached, graded by the target own checkers.
Methodology-stage for this lane. The harness ships so difficulty can be re-measured against whichever model matters to the buyer.
Ground truth
| What is correct | The authored fault and its known remediation. For detection pairs, the real advisory and the real fix commit. |
|---|---|
| How it is established | Per-stage machine checks run against the live container. Offensive tasks score by rung reached; defensive tasks score by re-running the working exploit against the submitted patch. |
| Agreement | Deterministic and execution-based. No human judgement enters the score. |
How it is built
- 01
Author the vulnerable service
Each target is a real running service with a deliberately introduced flaw, containerized so it starts identically on every run. Targets are authored rather than scraped so the fault is known exactly.
- 02
Require a chain, not a bug
The hardest targets need several stages composed in order - injection through privilege escalation to data export, or request forgery through a forged token to remote execution. Single-step targets are kept only as the lower rungs of the difficulty range.
- 03
Cover non-web classes
Raw-socket memory corruption and cryptographic forgery targets are included so the suite measures more than web-application familiarity.
- 04
Build the subtask ladder
Every target ships per-stage checks, so a run that reaches stage three of five scores three rather than zero. This is what makes the suite usable as a reward signal rather than only as a pass/fail benchmark.
- 05
Validate exploit and patch against each other
The working exploit is run against the patched service and must fail, and against the unpatched service and must succeed. A target does not ship until both directions hold.
- 06
Mine detection pairs from real CVEs
Vulnerability-detection pairs are derived from real published advisories, each carrying the defective code, the fix, and a checker that distinguishes them.

We send real records in the format you would receive, with the field list and where each record came from. Access for evaluation is limited and covered by a mutual NDA.
