The Content Copy Protection & Prevent Image Save WordPress plugin through 1.3 does not check for CSRF when saving its settings, not perform any validation and sanitisation on them, allowing attackers to make a logged in administrator set arbitrary XSS payloads in them.
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
