CVE-2026-8995

Estado: AplazadaMedia (4.3)—

The Poll Maker – Versus Polls, Anonymous Polls, Image Polls plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to and including 6.3.7. This is due to insufficient access controls on the 'ays_poll_get_user_information' AJAX action, which serializes and returns the complete WP_User object — including the user_pass (bcrypt password hash), user_email, user_login, user_registered, roles, and all capabilities — without any nonce verification or capability check beyond is_user_logged_in().

This makes it possible for authenticated attackers, with subscriber-level access and above, to retrieve sensitive account data including their own password hash, which WordPress does not expose through any of its standard interfaces and which can be leveraged for offline password-cracking attacks.
