Intended Uses
- LLM fine-tuning for secure code generation and secure code review.
- SAST / vulnerability-detection research (classifiers, detectors, benchmarks).
- AI security / agent safety evaluation of coding assistants and agentic tools (via
trajectories/trajectories.jsonl). - Academic research on insecure-coding patterns, remediation, and LLM agent vulnerabilities.
- Benchmark creation for secure-coding and agent-safety capabilities of models.
- Developer training and secure-coding workshops.
Out-of-Scope / Prohibited Uses
- Deploying the vulnerable code in a production system.
- Using the examples to attack systems you do not own or are not authorized to test.
- Training models to generate exploits without corresponding remediation context.

Coverage
Vulnerability classes (29+): SQL Injection, XSS, Command/OS Injection, SSRF, XXE, Path Traversal, File Upload, Insecure Deserialization, CSRF, Authentication, Authorization, IDOR, JWT, OAuth, Session Management, Secrets Exposure, Cryptography Misuse, Logging Sensitive Data, Business Logic, Rate Limiting, Input Validation, Header Injection, Clickjacking, Race Conditions, Open Redirect, Prompt Injection, MCP Security, RAG Security, Prototype Pollution, LDAP Injection.
Application domains: REST APIs, GraphQL, gRPC-style services, CLI tools, microservices, serverless, background workers, authentication systems, payment/banking, healthcare (FHIR/PHI), e-commerce, IoT, RAG pipelines, and MCP/agent tooling.
LLM threat categories (trajectories): indirect & direct prompt injection, RAG poisoning, tool-use abuse (SSRF / file write / email / webhook / notify), jailbreaks (DAN / role-play / obfuscation / hypothetical / translation / authority), and data exfiltration (pixel beacons, markdown images, log smuggling, prompt-based encoding).
Statistics
Full distributions are in statistics/:
language_distribution.csv, framework_distribution.csv, severity_distribution.csv,
cwe_distribution.csv, owasp_distribution.csv, plus an ASCII charts.txt.
Headline split (v1.2.0, 470 code records):

| Python | 66 | 14% |
| Go | 50 | 11% |

Leaderboard / Benchmark
The benchmark split (47 records) is a curated, balanced subset for leaderboard-style evaluation of secure-code
generation and vulnerability-detection models. Suggested tasks:
- Vulnerability classification — given
vulnerable_code, predictcwe/owasp/severity. - Secure-code synthesis — given
vulnerable_code+description, generatesecure_code(scored vs. reference patch). - Patch generation — produce a unified
patchfrom vulnerable→secure. - Agent safety (trajectories) — given a
trajectories/trajectories.jsonlturn sequence, flag theis_attackturn and predictmitigation.
Report metrics (precision/recall/F1 for classification; BLEU/CodeBLEU + functional correctness for synthesis) with the
benchmark split only, and cite this dataset.
Validation
Automated checks live in scripts/validate.py and a report in
validation/validation_report.md. The v1.2.0 run is PASS:
- JSON validity per line ✅
- No duplicate record ids ✅
- All required fields present and non-empty (tags/metadata typed) ✅
- OWASP / OWASP-API / OWASP-LLM / CWE format consistency ✅
- Python examples compile (
ast.parse) ✅ - Label consistency (severity ∈ {Low,Medium,High,Critical}) ✅
Reproduce:
python3 scripts/build.py
python3 scripts/validate.py
python3 scripts/statistics.py
Reproducibility
All examples are hand-authored (no template-renamed duplicates). Source records live in scripts/data.py and
scripts/data_ext*.py; trajectories in scripts/trajectories.py. The build uses a fixed seed (42) for deterministic
train/validation/test splits. See manifest.json.
Limitations
- v1.2.0 covers 470 curated code examples + 30 trajectories; not exhaustive across every CWE/language permutation.
- Compilation/formatting is verified for Python; other languages are reviewed by hand (no language compilers bundled, except best-effort heuristics).
- Examples are illustrative and may omit full project context (imports, config) needed to run standalone.
- Severity is CVSS-style guidance from the author, not a formally scored CVSS vector.
- Trajectories are synthetic agent scenarios for safety research, not transcripts of real systems.
Ethical Considerations & Responsible AI
The dataset teaches defense. Vulnerable code is provided only with explicit remediation and never as a how-to for attack. It must not be used to compromise systems without authorization. Models trained on it should be evaluated for safe, remediation-aware generation. Maintainers will review contributions to avoid adding weaponized, context-free exploits.
