CVE-2025-12019: Mer.vin Featured Image

Medium severity, CVSS 5.5. EPSS: 0.5% chance of exploitation in the next 30 days.

The Featured Image plugin for WordPress is vulnerable to Stored Cross-Site Scripting via image metadata in all versions up to, and including, 2.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
