Stored Cross-Site Scripting Vulnerability in WP Mailto Links – Protect Email Addresses Plugin for WordPress

CVE-2023-5109 · MEDIUM Severity

CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N

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.
