security-scan

Run a security scan on this codebase.

Changed files (focus here first)

!git diff --name-only HEAD~1 2>/dev/null || git diff --name-only origin/main...HEAD 2>/dev/null || echo "all files — no git diff available"

Prioritize scanning the files listed above. If the output says "all files", scan the entire codebase.

Security checks

For each check, search the changed files first. If changed files is "all files", search the entire codebase excluding node_modules/, dist/, .git/, vendor/, and *.min.js.

1. Hardcoded secrets

Search for patterns like password=, api_key=, secret=, token=, passwd=, private_key= followed by a literal value (not a variable reference or environment variable lookup).

Exclude:

• Files in test/, spec/, __tests__/ directories
• Files ending in .example, .sample, .template
• Lines that contain process.env, os.environ, getenv, ${, $(, or config.get

2. SQL injection risk

Search for SQL keywords (SELECT, INSERT, UPDATE, DELETE, WHERE, FROM) appearing inside f-strings (Python), template literals (JavaScript/TypeScript), or string concatenation patterns where a variable is embedded directly. Look for patterns like:

• f"SELECT ... {variable}
• `SELECT ... ${variable}`
• "SELECT " + variable

3. XSS vectors

Search .js and .ts files for innerHTML being assigned a value that includes a variable: element.innerHTML = , .innerHTML +=. Flag any assignment that does not call a sanitization function (DOMPurify.sanitize, sanitize(, escapeHtml().

4. Unvalidated inputs

Search for patterns where request body or parameters are passed directly to a database function without an intervening validation step. Look for req.body., request.data, request.form, params[ in close proximity (within 5 lines) to database calls (query(, execute(, find(, .save(, .create().

5. Insecure defaults

Search for:

• DEBUG = True or DEBUG=True (Python)
• NODE_ENV not set to production in deployment configuration files
• verify=False in Python requests calls
• CORS configured to allow all origins: cors({ origin: '*' }), Access-Control-Allow-Origin: * in non-development config files
