Blog2Social: Social Media Auto Post & Scheduler <= 8.9.0 - Missing Authorization to Authenticated (Subscriber+) Delete Arbitrary B2S Post Records via 'postId' Parameter
The Blog2Social: Social Media Auto Post & Scheduler plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 8.9.0. This is due to a missing ownership verification in the B2S_Post_Tools::deleteUserPublishPost() and B2S_Post_Tools::deleteUserSchedPost() functions, neither function includes a blog_user_id constraint in its database query, allowing authenticated attackers to soft-delete any user's B2S post records by supplying arbitrary sequential wp_b2s_posts.id values via the 'postId' parameter. This makes it possible for authenticated attackers to delete other users' published and scheduled social media post records, disrupting content publishing workflows.
