## What it looks like

A cleanup or media handler deletes a path supplied by an unauthorized user.

## Why it matters

Site files or backups may be removed.

## What to check

Audit delete actions for capabilities, ownership, and path confinement.

## 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 path traversal reference](https://community.owasp.org/attacks/Path_Traversal), [WordPress roles and capabilities](https://developer.wordpress.org/apis/security/user-roles-and-capabilities/).
