Input handling

Unvalidated Input Check — Does Request Data Flow Straight Into Writes or Shell?

DevMeth checks the 48 known AI-code failure patterns — not a penetration test or a security guarantee.

What the issue is

When request data flows straight into a database write or a shell command without validation, a crafted value can corrupt data or run unintended commands on your server.

Why AI tools generate it

AI tools often pass request values directly into a write or exec() to save a step, skipping the schema check that would catch hostile shapes.

How DevMeth detects it

A code scan traces request-originated data into database writes or shell sinks and flags any path that reaches the sink unvalidated.

The fix, in three steps

Validate and schema-check request data before it reaches any DB-write or shell sink, and never feed raw input to exec(). Three steps.
