Summary
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.

          "value": "The Email Encoder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the \u0027eeb_mailto\u0027 shortcode in versions up to, and including, 2.1.8 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. A partial patch was issued in version 2.1.8. The vulnerability was fully patched in 2.1.9."
