Descriptions

The Smash Balloon Social Post Feed WordPress plugin before 4.0.1 did not have any privilege or nonce validation before saving the plugin's setting. As a result, any logged-in user on a vulnerable site could update the settings and store rogue JavaScript on each of its posts and pages.
