OFFENSIVE-DEFENSIVE RL ENVIRONMENTS
Exploit & Patch Tasks
Containerized vulnerable services with working exploits, patches, and a machine-gradeable subtask ladder - multi-stage chains, not single-bug toys.

Target manifest with subtask ladder
Real structure. Service internals, exploit steps, and flag material are withheld - these are graded targets.

}Record shape
Every field, its type, whether it can be null, and a representative value.
| Field | Type | Constraint | Description |
|---|---|---|---|
| target_id | string | required | Stable identifier for the containerized target. |
| chain | string[] | required | Ordered exploitation stages the target requires. e.g. ["injection", "privilege escalation", "data export"] |
| service/ | directory | required | The vulnerable service source and its container definition. |
| exploit/ | directory | required | A working exploit, retained privately and used to validate the patch. |
| patch/ | directory | required | The remediation the defensive variant of the task is graded against. |
| checker/ | directory | required | Per-stage machine checks that produce the subtask ladder score. |
| subtasks[] | object[] | required | Ordered rungs with individual pass conditions, enabling partial credit. |
| class | enum | required | web | memory-corruption | cryptographic. e.g. cryptographic |
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.
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.
How we validate
What each evaluation measures and how it is run. Where no benchmark is published, we show the methodology and say so.
Exploit-patch round trip
Measures
Whether the shipped patch actually closes the hole the shipped exploit opens.
Method
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.
Result
Real measured: passes for every target in the reference tranche.
Stage reachability
Measures
Whether each rung of the ladder is independently reachable and independently checkable.
Method
Each subtask checker is exercised against a run that stops at that stage, confirming the ladder scores partial progress rather than collapsing.
Result
Real measured: verified per target before release.
Model difficulty
Measures
Where frontier models stop on the ladder.
Method
The shipped calibration harness runs any model against the targets and records the highest rung reached, graded by the target own checkers.
Result
Methodology-stage for this lane. The harness ships so difficulty can be re-measured against whichever model matters to the buyer.
Ground truth
What correct means for this data, and how it is established.
Ground truth
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.
Security Agent Training
Reward-bearing environments for agents that must find, exploit, and then remediate - with partial credit available at each rung of the subtask ladder.
Defensive Evaluation
Measure whether a model can produce a patch that actually closes the hole, verified by re-running the working exploit against the patched service.
Capability Measurement
Staged difficulty makes it possible to report where a model stops rather than a single pass/fail, which is what a capability evaluation needs.
How you load it
Delivery
Secure download, Docker Compose, Container registry
Formats
Docker image, Compose manifest, JSONL task index
Auth
Org-scoped credentials. Exploits and checkers are delivered under a restricted licence separate from the target images, so an evaluation set can be withheld from a training set.
Cadence
Continuous build. Tranches are cut monthly; a month of production is on hand at the volumes shown above.
# Bring up one target and score a rundocker compose -f targets/<id>/compose.yaml up -dbash 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.
