## What it looks like

An upload accepts a file based only on its name or claimed content type.

## Why it matters

A script may be stored where it can be executed or served to visitors.

## What to check

Verify actual file type and prevent execution in upload storage.

## Documentation

This is an exploit pattern to check in installed components, not a claim that every WordPress site has this flaw. Confirm the product and version against its advisories before treating a site as affected. See [OWASP file upload guidance](https://cheatsheetseries.owasp.org/cheatsheets/File_Upload_Cheat_Sheet.html).
