Exploiting this issue could allow an attacker to inject key/value �properties� into JavaScript objects, potentially allowing for execution of arbitrary JavaScript in a user�s session if they can trick that user into clicking a link. WordPress versions 4.2.x ranging from 4.2 and up to (and including) 4.2.31 are vulnerable.
