AI coders copy localhost and dev URLs into production code, leaking internal services and breaking security. Here is why it happens, what it costs, and how to stop it without slowing down.
AI coding assistants generate fast code, but they skip request size checks and input validation. Learn why that breaks your API and how to enforce limits cheaply.
AI tools copy hardcoded secrets into code, making leaks worse. Learn to keep credentials out of source and prompts, and rotate them if exposed.
A list endpoint with no LIMIT clause is correct at ten test rows and a resource exhaustion risk at production scale, and no small dataset will ever catch the difference.
A recursive object merge that copies every key from user input, including __proto__, can rewrite the default properties of every plain object in the running process.
A follow-up commit that removes .env from the working tree leaves the original commit, and every secret in it, fully readable in the repository's history.
Redirecting to a next query parameter after login without validating it against your own host turns a trusted login page into a launchpad for phishing links.
Skipping the USER instruction in a Dockerfile is the default, not a deliberate choice, and it quietly removes one of the two layers standing between a container bug and the host.
An endpoint that fetches a resource by its route parameter without checking ownership will happily return anyone's data, and sequential IDs make it trivial to find them all.
