Sync Feedly <= 1.0.1 - Cross-Site Request Forgery to Sync Trigger

Description

The Sync Feedly plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.0.1. This is due to missing or incorrect nonce validation on the crsf_cron_job_func function. This makes it possible for unauthenticated attackers to trigger content synchronization from Feedly, potentially creating multiple posts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
