• Severity: medium (CVSS 5.4 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.4% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-05-13 · updated 2026-06-17
• Weakness: CWE-862

Description

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.
