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.
The Blog2Social WordPress plugin versions up to 8.9.0 contain a missing authorization vulnerability allowing authenticated attackers to delete other users' social media posts. This vulnerability affects the deleteUserPublishPost() and deleteUserSchedPost() functions which lack proper ownership verification.
