Review paths, not isolated patterns

A risky function call is not automatically a vulnerability. A useful code review connects an attacker-controlled source to a sensitive sink, checks every transformation and guard in between, and states the conditions that make the path reachable.

  • Prioritize routes, handlers, authorization, uploads, and CI configuration
  • Trace sources such as request fields, GraphQL variables, queues, and environment values
  • Review sinks such as SQL, shell, filesystem, templates, redirects, and outbound requests
  • Check cross-tenant and role boundaries alongside injection risks

Make each candidate independently checkable

Pin the repository revision and keep each result tied to a real file, line, and small code excerpt. Validation should test whether the route is reachable, the input is controlled, and the guard actually protects every relevant path.

  • Record repository and commit so line references remain reproducible
  • Include source, data flow, sink, exploit condition, and counter-evidence
  • Separate confirmed behavior from assumptions that require runtime testing
  • Keep credentials and unrelated source out of exported reports

Use language context where your team works

Singapore product teams commonly operate mixed application estates. A review should account for the frameworks and code paths in the repository rather than relying on a generic rule list; dynamic behavior still needs DAST or an authorized manual check.

  • Cover backend and frontend code, build configuration, and infrastructure definitions where in scope
  • Map findings to the repository owner and the control that needs a change
  • Use DAST when deployment, authentication, or runtime configuration determines impact
  • Retest the corrected path on the new revision before closure
