Subject: Re: [FD] Photo Manager Pro 4.4.0 iOS - Code Execution Vulnerability

This looks like a reflected XSS, not a code execution vulnerability as the
term is commonly understood.

> Solution - Fix & Patch:

> Security Risk:

> The security risk of the code execution vulnerability in the photo manager

of the state, the other serves and protects the people. When the military
becomes both, then the enemies of the state tend to become the people.”
