CVE-2026-8994

The Login with NEAR plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 0.3.3. The ajaxLoginWithNear() function — registered as a wp_ajax_nopriv action and therefore reachable by unauthenticated users — accepts an attacker-supplied account POST parameter and issues a valid WordPress authentication cookie based solely on a substring check for .near, with no nonce verification, cryptographic signature validation, challenge-response exchange, or any proof that the requester controls the corresponding NEAR wallet. This makes it possible for unauthenticated attackers to log in as any existing WordPress user, including administrators, whose email address matches the deterministic @near.org pattern derived from the supplied account value. If no matching user exists, the handler automatically creates and authenticates a new WordPress account for the attacker-controlled identifier, providing a further avenue for unauthorized account creation.
