CVE-2025-1475: Whyun Wpcom Member

Critical severity, CVSS 9.8. EPSS: 0.6% chance of exploitation in the next 30 days.

The WPCOM Member plugin for WordPress is vulnerable to authentication bypass in all versions up to, and including, 1.7.5. This is due to insufficient verification on the 'user_phone' parameter when logging in. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, if SMS login is enabled.
