Description
The Blog2Social: Social Media Auto Post & Scheduler plugin for WordPress is vulnerable to unauthorized data loss in all versions up to, and including, 8.8.2. This is due to the resetSocialMetaTags() function only verifying that the user has the 'read' capability and a valid b2s_security_nonce, both of which are available to Subscriber-level users, as the plugin grants 'blog2social_access' capability to all roles upon activation, allowing them to access the plugin's admin pages where the nonce is output. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete all _b2s_post_meta records from the wp_postmeta table, permanently removing all custom social media meta tags for every post on the site.
