## Technical details

The vulnerability exists in YOOtheme Pro's publicly accessible image transformation handler, which incompletely binds normalized image operations and output destinations to request signatures. An attacker can reuse a signature from a legitimate public image URL, inject additional image operations to traverse directories, and write a PNG/PHP polyglot file to an executable public media directory, achieving unauthenticated remote code execution.
