CVE-2026-6963: Shahariaazam Wp Mail Gateway

High severity, CVSS 8.8. EPSS: 0.6% chance of exploitation in the next 30 days.

The WP Mail Gateway plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on the wmg_save_provider_config AJAX action in all versions up to, and including, 1.8. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update SMTP settings and redirect mail which can be used for privilege escalation by triggering a password reset email and using that to access and administrator's account.
