Description

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 `<account>@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.

Affected WordPress components

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.
