CVE-2023-5109: Ironikus Wp Mailto Links

Medium severity, CVSS 5.4. EPSS: 0.5% chance of exploitation in the next 30 days.

The WP Mailto Links – Protect Email Addresses plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'wpml_mailto' shortcode in versions up to, and including, 3.1.3 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This was partially patched in version 3.1.3 and fully patched in version 3.1.4.

Affected products

• Ironikus Wp Mailto Links: before 3.1.4 (fixed in 3.1.4)
