Easy Social Icons WordPress plugin

It is discovered that insufficient validation is performed on the 'image_file' parameter enabling arbitrary JavaScript to be injected. On top of that no random tokens are used to prevent CSRF attacks. By combining these vulnerabilities an attacker could for example trick an admin into setting a persistent XSS payload on the public WordPress page.

Mitigation:

Upgrade to version 1.2.3
