CVE-2026-7051 | 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.

Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:L)
Attackers could change some data, but it’s limited—not everything goes.
Availability (A:L)
Might cause slowdowns, glitches, or partial disruption—not a full brick.
