# SAST Security Plugin


Static Application Security Testing (SAST) for comprehensive code vulnerability detection across multiple languages, frameworks, and security patterns.


Capabilities


- **Multi-language SAST**: Python, JavaScript/TypeScript, Java, Ruby, PHP, Go, Rust

- **Tool integration**: Bandit, Semgrep, ESLint Security, SonarQube, CodeQL, PMD, SpotBugs, Brakeman, gosec, cargo-clippy

- **Vulnerability patterns**: SQL injection, XSS, hardcoded secrets, path traversal, IDOR, CSRF, insecure deserialization

- **Framework analysis**: Django, Flask, React, Express, Spring Boot, Rails, Laravel

- **Custom rule authoring**: Semgrep pattern development for organization-specific security policies


Use this skill when


Use for code review security analysis, injection vulnerabilities, hardcoded secrets, framework-specific patterns, custom security policy enforcement, pre-deployment validation, legacy code assessment, and compliance (OWASP, PCI-DSS, SOC2).


**Specialized tools**: Use `security-secrets.md` for advanced credential scanning, `security-owasp.md` for Top 10 mapping, `security-api.md` for REST/GraphQL endpoints.


Do not use this skill when


- You only need runtime testing or penetration testing

- You cannot access the source code or build outputs

- The environment forbids third-party scanning tools


Instructions


1. Identify the languages, frameworks, and scope to scan.

2. Select SAST tools and configure rules for the codebase.

3. Run scans in CI or locally with reproducible settings.

4. Triage findings, prioritize by severity, and propose fixes.


Safety


- Avoid uploading proprietary code to external services without approval.

- Require review before enabling auto-fix or blocking releases.


SAST Tool Selection


Python: Bandit


bash
# Installation & scan
pip install bandit
bandit -r . -f json -o bandit-report.json
bandit -r . -ll -ii -f json  # High/Critical only

**Configuration**: `.bandit`

yaml
exclude_dirs: ['/tests/', '/venv/', '/.tox/', '/build/']
tests: [B201, B301, B302, B303, B304, B305, B307, B308, B312, B323, B324, B501, B502, B506, B602, B608]
skips: [B101]

JavaScript/TypeScript: ESLint Security


bash
npm install --save-dev eslint @eslint/plugin-security eslint-plugin-no-secrets
eslint . --ext .js,.jsx,.ts,.tsx --format json > eslint-security.json

**Configuration**: `.eslintrc-security.json`

json
{
  "plugins": ["@eslint/plugin-security", "eslint-plugin-no-secrets"],
  "extends": ["plugin:security/recommended"],
  "rules": {
    "security/detect-object-injection": "error",
    "security/detect-non-literal-fs-filename": "error",
    "security/detect-eval-with-expression": "error",
    "security/detect-pseudo-random-prng": "error",
    "no-secrets/no-secrets": "error"
  }
}

Multi-Language: Semgrep


bash
pip install semgrep
semgrep --config=auto --json --output=semgrep-report.json
semgrep --config=p/security-audit --json
semgrep --config=p/owasp-top-ten --json
semgrep ci --config=auto  # CI mode

**Custom Rules**: `.semgrep.yml`

yaml
rules:
  - id: sql-injection-format-string
    pattern: cursor.execute("... %s ..." % $VAR)
    message: SQL injection via string formatting
    severity: ERROR
    languages: [python]
    metadata:
      cwe: "CWE-89"
      owasp: "A03:2021-Injection"

  - id: dangerous-innerHTML
    pattern: $ELEM.innerHTML = $VAR
    message: XSS via innerHTML assignment
    severity: ERROR
    languages: [javascript, typescript]
    metadata:
      cwe: "CWE-79"

  - id: hardcoded-aws-credentials
    patterns:
      - pattern: $KEY = "AKIA..."
      - metavariable-regex:
          metavariable: $KEY
          regex: "(aws_access_key_id|AWS_ACCESS_KEY_ID)"
    message: Hardcoded AWS credentials detected
    severity: ERROR
    languages: [python, javascript, java]

  - id: path-traversal-open
    patterns:
      - pattern: open($PATH, ...)
      - pattern-not: open(os.path.join(SAFE_DIR, ...), ...)
      - metavariable-patter

❓ Frequently Asked Questions

Can this replace a dedicated SAST tool?

AI-based security review is complementary to SAST tools. Use it as a first-pass filter, not a replacement.

Is Security Scanning Security Sast compatible with Cursor and VS Code?

Yes — this skill works with any AI coding assistant including Cursor, VS Code with Copilot, and JetBrains IDEs.

Do I need specific dependencies for Security Scanning Security Sast?

Check the install command and Works With section. Most code skills only require the AI assistant and your codebase.

How do I install Security Scanning Security Sast?

Copy the install command from the Terminal tab and run it. The skill downloads to ./skills/security-scanning-security-sast/SKILL.md, ready to use.

Can I customize this skill for my team?

Absolutely. Edit the SKILL.md file to add team-specific instructions, examples, or workflows.

⚠️ Common Mistakes to Avoid

Only scanning surface-level issues

Deep security review requires understanding your app architecture, not just regex patterns.

Skipping validation

Always test AI-generated code changes, even for simple refactors.

Missing dependency updates

Check if the skill requires updated dependencies or new packages.
