Add a timeout to HTTP requests. Use AbortSignal.timeout() for fetch or the timeout option for axios.
id: ops.dockerfile-secrets-in-env🔗
Dockerfile bakes secrets or credentials into image layers via ENV or ARG instructions
Próximamente - estamos escribiendo explicaciones detalladas para cada comprobación.
Never pass secrets via ENV or ARG — they persist in image history. Use Docker BuildKit secrets (RUN --mount=type=secret), environment variables injected at container start, or a secrets manager.
id: ops.no-version-control🔗
No Git repository detected. Version control is essential for collaboration and code recovery.
Failing to address this issue can lead to security vulnerabilities, operational failures, or data exposure, compromising the safety and reliability of your application.
Initialize a Git repository with git init and commit your code. Regular commits provide history, collaboration, and a safety net for recovery.
id: ops.no-graceful-shutdown🔗
Server lacks graceful shutdown handling, risking dropped requests and data loss on restart.
Failing to address this issue can lead to security vulnerabilities, operational failures, or data exposure, compromising the safety and reliability of your application.
Listen for SIGTERM and SIGINT signals. Gracefully close server connections and drain in-flight requests before exiting.
id: ops.missing-observability🔗
No metrics, tracing, or structured telemetry hooks
Without observability, you cannot detect outages, debug performance regressions, or measure the impact of deployments. Incidents become blind hunts (CWE-778).
Add metrics, tracing, or structured logging to your service. Use libraries like prom-client, dd-trace, or OpenTelemetry to emit observable telemetry.
id: ops.secret-rotation-friction🔗
Hardcoded secret paths impeding automated rotation
When secrets are hardcoded, rotating them requires a code change, review, build, and deployment. This friction leads to long-lived secrets and increases blast radius if a credential is leaked (CWE-798).
Load secrets from a secret manager (e.g., AWS Secrets Manager, HashiCorp Vault, Azure Key Vault) instead of hardcoding them. This enables automated rotation without redeploying code.
id: ops.env-drift🔗
.env.example is out of sync with runtime environment variable usage
Drift between `.env.example` and runtime usage causes deployment failures, hidden misconfigurations, and secret sprawl. New developers may miss required variables (CWE-1188).
Keep .env.example in sync with the variables your code reads at runtime. Add a CI check or lint rule that flags missing or unused environment variables.
id: ops.dockerfile-runs-as-root🔗
Container image has no non-root USER directive — all processes run as root
Próximamente - estamos escribiendo explicaciones detalladas para cada comprobación.
Create a non-root user and switch to it before CMD/ENTRYPOINT: RUN addgroup -S app && adduser -S app -G app followed by USER app.
id: ops.debug-mode-enabled🔗
Debug / verbose logging enabled in production config or source code
Improper logging and monitoring configurations can expose sensitive debugging details to attackers or fail to provide alert visibility during active service outages.
Disable debug logging and verbose mode in production. Use environment-specific config files or flags.
id: ops.hardcoded-localhost🔗
localhost URL is hardcoded rather than configured via environment variables.
Exposing secrets or environment configuration details in source code makes them accessible to unauthorized users and increases the threat surface of the infrastructure.
Replace localhost with a configurable base URL. Use environment variables or a config module.
id: ops.no-health-check🔗
No health check endpoint is defined, making it harder to monitor service availability.
Failing to address this issue can lead to security vulnerabilities, operational failures, or data exposure, compromising the safety and reliability of your application.
Add a /health or /healthz endpoint that returns a 200 status when your service is operational.
id: ops.missing-structured-logging🔗
Logging uses unstructured format, making log analysis and monitoring more difficult.
Improper logging and monitoring configurations can expose sensitive debugging details to attackers or fail to provide alert visibility during active service outages.
Use a structured logging library like pino or winston with JSON output for machine-readable logs.
id: ops.dockerfile-no-healthcheck🔗
Dockerfile has no HEALTHCHECK instruction — container orchestrators cannot detect unhealthy state
Próximamente - estamos escribiendo explicaciones detalladas para cada comprobación.
Add a HEALTHCHECK instruction, e.g.: HEALTHCHECK --interval=30s --timeout=3s CMD curl -f http://localhost:8080/health || exit 1
id: ops.missing-dockerignore🔗
Dockerfile is present without a .dockerignore — build context may include node_modules, .env files, or other sensitive data
Próximamente - estamos escribiendo explicaciones detalladas para cada comprobación.
Add a .dockerignore file listing directories and files to exclude from the build context: node_modules, .env, .git, *.log, dist, coverage.
id: ops.hardcoded-port🔗
Server port number hardcoded rather than configured via environment variables.
Failing to address this issue can lead to security vulnerabilities, operational failures, or data exposure, compromising the safety and reliability of your application.
Use process.env.PORT with a fallback value. Never hardcode port numbers in source.
id: ops.insecure-file-permissions🔗
fs.chmod call that may set overly permissive file permissions.
Failing to address this issue can lead to security vulnerabilities, operational failures, or data exposure, compromising the safety and reliability of your application.
Use the most restrictive file permissions possible. Prefer 0o600 for secrets, 0o644 for config.
id: dependencies.missing-lockfile🔗
No lockfile found. Unpinned dependencies are a reproducibility and supply-chain risk.
Unpinned dependency versions make builds non-deterministic and expose the application to unexpected breaking updates or supply-chain attacks.
Commit a lockfile (package-lock.json, yarn.lock, pnpm-lock.yaml, Gemfile.lock, go.sum, composer.lock) or Maven/Gradle reproducibility artifacts (mvnw, gradle.lockfile) to pin exact dependency versions.

Failing to address this issue can lead to security vulnerabilities, operational failures, or data exposure, compromising the safety and reliability of your application.
Replace deprecated functions with their recommended alternatives. Check the library migration guide.
id: configuration.secrets-in-source🔗
Secrets in source rather than environment variables
Exposing secrets or environment configuration details in source code makes them accessible to unauthorized users and increases the threat surface of the infrastructure.
Use environment variables instead. Store the secret value in process.env and reference it by key name.
id: configuration.default-credentials🔗
Default or hardcoded credentials are used instead of unique, environment-specific credentials.
Exposing secrets or environment configuration details in source code makes them accessible to unauthorized users and increases the threat surface of the infrastructure.
Change default credentials immediately. Use strong, unique passwords and store them in environment variables.
id: configuration.missing-ssl-verification🔗
rejectUnauthorized set to false, disabling TLS certificate validation.
Failing to address this issue can lead to security vulnerabilities, operational failures, or data exposure, compromising the safety and reliability of your application.
Never set rejectUnauthorized to false in production. Use proper TLS certificates.
id: configuration.no-env-separation🔗
Configuration does not differentiate between development, staging, and production environments.
Failing to address this issue can lead to security vulnerabilities, operational failures, or data exposure, compromising the safety and reliability of your application.
Create separate config files per environment or use environment variables to differentiate dev/staging/prod settings.
id: configuration.insecure-cookie-flags🔗
Cookie set without explicit security flags (HttpOnly, Secure, SameSite).
Weak session identifiers or insecure cookies can be intercepted or predicted by attackers, leading to session hijacking and unauthorized account access.
Set HttpOnly, Secure, and SameSite=Strict on session cookies.
id: data-exposure.verbose-errors🔗
Error responses include stack traces or internal details, leaking implementation information to clients.
Failing to address this issue can lead to security vulnerabilities, operational failures, or data exposure, compromising the safety and reliability of your application.
Catch errors in your middleware and return generic error messages to clients. Log the full error server-side only.
id: data-exposure.pii-in-responses🔗
API responses include personally identifiable information without proper filtering.
Failing to address this issue can lead to security vulnerabilities, operational failures, or data exposure, compromising the safety and reliability of your application.
Filter API responses to exclude PII fields. Use select or projection to return only necessary fields.
id: data-exposure.no-response-filtering🔗
API responses return full database rows without filtering sensitive or unnecessary fields.
Failing to address this issue can lead to security vulnerabilities, operational failures, or data exposure, compromising the safety and reliability of your application.
Select only the fields you need from database queries. Never return full rows to clients without filtering.
id: data-exposure.unprotected-sensitive-sql-columns🔗
Storing highly sensitive fields (like SSNs, cards, or plain API keys) without encryption or hashing poses high data exposure risks.
Unsafe database interactions and weak permissions allow SQL injection or unauthorized data exposure, compromising data confidentiality and integrity.
Encrypt sensitive data columns at rest, or use hashed/digest representations for fields like passwords or API tokens.
id: data-exposure.html-form-pii-exposure🔗
Forms should not keep PII in hidden inputs or expose sensitive autofill settings on fields
Failing to address this issue can lead to security vulnerabilities, operational failures, or data exposure, compromising the safety and reliability of your application.
Avoid storing PII in hidden inputs and set autocomplete="off" on sensitive fields. Keep sensitive data server-side when possible.
id: data-exposure.plaintext-secret-in-email🔗
Detects license keys, tokens, or API keys rendered in plain-text email bodies without warning that email is not encrypted in transit
Sending license keys or credentials in plaintext email bodies exposes them to interception or unauthorized access, as standard email is not encrypted in transit (CWE-319).
Add a warning to the plain-text email body that email is not encrypted in transit. Consider omitting the secret from the plain-text part entirely, or linking to a secure dashboard instead.
id: data-exposure.composite-pii🔗
Multiple PII attributes collected together enabling re-identification
Combining seemingly harmless fields can uniquely identify individuals. This violates privacy regulations (GDPR, CCPA) and exposes users to identity theft (CWE-359).
Split or pseudonymise composite PII fields. Avoid storing multiple identifying attributes in the same record or API response.
id: data-exposure.derived-identifiers🔗
Derived or synthetic identifiers that enable record linkage across sessions or datasets
Derived identifiers can re-identify pseudonymised users and track them without their consent. This undermines privacy guarantees and may violate regulations (CWE-359).
Avoid creating derived identifiers from user data for tracking or correlation. Use anonymous session tokens that cannot be reversed to identify the user.
id: data-exposure.unredacted-logs🔗
PII or sensitive data written to logs without redaction
Logs are often stored in plaintext, aggregated across services, and accessible to many engineers. Unredacted PII in logs is a frequent source of data breaches and compliance violations (CWE-532).
Redact or mask sensitive fields before logging. Use a structured logging library with automatic PII scrubbing or log only non-sensitive summary data.
id: data-exposure.localstorage-sensitive-data🔗
Storing sensitive data (password, token, secret) in localStorage is insecure.
Failing to address this issue can lead to security vulnerabilities, operational failures, or data exposure, compromising the safety and reliability of your application.
Do not store sensitive data in localStorage. Use httpOnly cookies or secure server-side storage.
id: data-exposure.debug-artifacts🔗
Debugger statement or debug import left in production code, potentially exposing runtime state.
Improper logging and monitoring configurations can expose sensitive debugging details to attackers or fail to provide alert visibility during active service outages.
Remove debugger statements and debug imports before deploying to production.
id: data-exposure.hardcoded-ip🔗
A literal IP address in source code, which may leak internal infrastructure details.
Exposing secrets or environment configuration details in source code makes them accessible to unauthorized users and increases the threat surface of the infrastructure.
Move IP addresses to configuration or environment variables. Use DNS names where possible.
