CVE-2026-4330— WordPress plugin Blog2Social: Social Media Auto Post & Scheduler 安全漏洞

Blog2Social: Social Media Auto Post & Scheduler <= 8.8.3 - Authenticated (Subscriber+) Insecure Direct Object Reference to Arbitrary Post Schedule Modification via 'b2s_id' Parameter

This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify, reschedule, or delete other users' scheduled social media posts.
