CVE-2026-8994: CWE-287 Improper Authentication in learnnearclub Login with NEAR
The Login with NEAR WordPress plugin up to version 0. 3. 3 contains an authentication bypass vulnerability. The vulnerable ajaxLoginWithNear() function allows unauthenticated users to log in as any WordPress user whose email matches the pattern <account>@near. org by supplying a crafted account parameter. This occurs because the function only checks for the substring '. near' without verifying ownership of the NEAR wallet or using cryptographic validation. Additionally, if no matching user exists, the plugin creates and authenticates a new account for the attacker. This vulnerability can lead to unauthorized access and privilege escalation, including administrator accounts.
AI Analysis
Technical Summary
CVE-2026-8994 is an authentication bypass vulnerability in the Login with NEAR WordPress plugin (up to version 0.3.3). The ajaxLoginWithNear() function, exposed as a wp_ajax_nopriv action, accepts an attacker-controlled 'account' POST parameter and issues a valid WordPress authentication cookie based solely on a substring check for '.near'. It lacks nonce verification, cryptographic signature validation, or any proof of control over the NEAR wallet. This allows unauthenticated attackers to log in as any existing user with an email matching '<account>@near.org' or create new authenticated accounts if none exist. The vulnerability impacts confidentiality, integrity, and availability of affected WordPress sites.
Potential Impact
An attacker can bypass authentication controls to log in as any existing WordPress user, including administrators, or create new authenticated accounts without authorization. This compromises site confidentiality, integrity, and availability, potentially allowing full site takeover or unauthorized actions under privileged accounts.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the ajaxLoginWithNear() endpoint if possible or disable the Login with NEAR plugin to prevent exploitation.
