Integrate ShellCheck with Vulnetix. Lint shell scripts for bugs and security issues, convert to SARIF, and upload results.
Install & scan
$ uv run --with shellcheck-py shellcheck --version $ # ShellCheck doesn't output SARIF natively - use JSON + converter uv run --with shellcheck-py shellcheck -f json1 script.sh > shellcheck.json # Or with shellcheck-sarif converter (requires Rust/cargo): # cargo install shellcheck-sarif # shellcheck -f json script.sh | shellcheck-sarif > shellcheck.sarif
Run ShellCheck in CI
Scan on every push and upload the report as a workflow artifact:
- name: Run ShellCheck
run: |
pip install shellcheck-py
find . -name '*.sh' -exec shellcheck -f json1 {} + > shellcheck.json
- name: Upload to Vulnetix
run: vulnetix upload --file shellcheck.json
How Vulnetix compares: better together
Vulnetix does not replace ShellCheck. Keep running it. Vulnetix sits on top of ShellCheck (and every other scanner you already own) turning disconnected tool outputs into one prioritised, fixable queue.
| Capability | Vulnetix | ShellCheck |
|---|---|---|
| Security coverage | ||
| SAST (static code analysis) | ✓ Built-in rules + Semgrep augmentation | ~ Static analysis narrowly scoped to shell scripts; flags command-injection/quoting/eval risks but no general-purpose code SAST |
| SCA / dependencies | ✓ 40+ ecosystems, transitive graph | ✗ |
| DAST (dynamic testing) | ~ Ingests DAST results; no native dynamic engine | ✗ |
| Container & image | ✓ Image CVEs, base image, Dockerfile | ✗ |
| IaC / misconfiguration | ✓ Terraform, k8s, CloudFormation | ✗ |
| Secret scanning | ✓ 1,000+ rules, source + binary + git history | ✗ |
| Cloud / CSPM | ✓ Cloud-posture findings, compliance tab | ✗ |
| Mobile (MAST) | ~ Ingests mobile scanner output; no native mobile engine | ✗ |
| License compliance | ✓ SPDX, copyleft/AGPL/SSPL policy | ✗ |
| SBOM generation | ✓ CycloneDX 1.7 + SPDX 2.3, cosign-signable | ✗ |
| Malware / supply-chain | ✓ De-duplicated corpus + install-time firewall (25+ registries) | ✗ |
| Network / infra vuln | ~ Ingests network scanner output; no native network scanner | ✗ |
| Fuzzing | ✗ Ingests fuzzing crashes; no native fuzzer | ✗ |
| Pentest / bug bounty | ✗ Ingests pentest/bug-bounty findings; not a testing service | ✗ |
| The Vulnetix orchestration layer | ||
| Cross-scanner dedup & one queue (ASPM) | ✓ Correlates every scanner into one prioritised queue with ownership routing | ✗ |
| Exploit-intel prioritisation | ✓ EPSS, CISA KEV, Coalition ESS, CWSS, Vulnetix LEV | ✗ |
| Reachability analysis | ✓ Tree-sitter + CVEAffected; direct/transitive/semantic | ✗ |
| Versioned VEX + audit trail | ✓ Immutable OpenVEX/CycloneDX, cosign-signable | ✗ |

What ShellCheck does well
- The de facto standard static analyzer for shell scripts (Bash, sh, dash, ksh), with 100+ checks
- Catches security-relevant issues: unquoted variables enabling word-splitting/injection, unsafe eval, command-substitution pitfalls
- Excellent developer ergonomics: precise wiki-linked diagnostics, editor plugins, and ubiquitous CI integration
- Multiple output formats including SARIF, JSON, CheckStyle XML, and GCC-style for flexible tooling
Where Vulnetix adds to it: ShellCheck is the shell-script linting core; Vulnetix ingests its SARIF into a cross-scanner deduplicated queue and surrounds it with the coverage ShellCheck never attempts (SCA, container, IaC, secrets, cloud, malware, SBOM) plus exploit-intel prioritisation, reachability, versioned VEX, and autofix. Vulnetix orchestrates ShellCheck's findings; it does not replace its shell-specific rule engine.
No migration, no rip-and-replace. ShellCheck keeps doing what it does best; Vulnetix adds the orchestration, exploit-intelligence prioritisation and remediation layer built for the way AppSec works today.
Centralise ShellCheck results in Vulnetix
Upload ShellCheck SARIF output to the Vulnetix platform to deduplicate findings, prioritise them with EPSS, CISA KEV and Coalition ESS exploit intelligence, and track remediation across every scanner in a single queue.
