What is CVE-2026-2840?

The Email Encoder – Protect Email Addresses and Phone Numbers plugin for WordPress is susceptible to stored cross-site scripting attacks via the 'eeb_mailto' shortcode. This weakness arises from inadequate input sanitization and output escaping, allowing authenticated users with contributor-level access or higher to inject malicious scripts into pages. When users access these compromised pages, the injected scripts execute, potentially leading to unauthorized actions or data exposure.
