LoginPress Pro <= 6.2.3 - Unauthenticated Authentication Bypass via Unverified OAuth Email in Spotify OAuth Callback
The LoginPress Pro plugin for WordPress is vulnerable to authentication bypass in versions up to and including 6.2.3 via the Spotify Social Login addon. This is due to the loginpress_on_spotify_login() function trusting the unverified 'email' field returned by Spotify's /v1/me endpoint and using it directly with get_user_by('email', $profile['email']) to identify and log in an existing WordPress account, without confirming that the Spotify user actually owns the email address (Spotify documents that the profile email is unverified) and without requiring the user to prove ownership of the matching WordPress account. This makes it possible for unauthenticated attackers to log in as any existing WordPress user, including Administrators, by registering a Spotify account using the targeted user's email address and authenticating via the Spotify provider.
Quick answer
LoginPress Pro should be reviewed and updated if it matches the affected versions. The recommended fix is to apply the vendor-supported patched version or the mitigation steps below, then retest the public website with Fixnx.

How to fix it
LoginPress Pro is affected by CVE-2026-12598, a authentication bypass issue in versions up to 6.2.3. Wordfence lists the official remediation as updating to version 6.2.4, or a newer patched version. Prioritize internet-facing WordPress sites, sites with public registration, customer portals, Elementor/page-builder surfaces, and admin workflows where the vulnerable feature is enabled. If immediate patching is not possible, disable the affected plugin or feature, restrict access, and monitor for exploitation until the update is installed.
- Inventory every WordPress site that has LoginPress Pro installed, including production, staging, multisite, client, and WooCommerce environments.
- Confirm the installed LoginPress Pro version and compare it with the affected range from the Wordfence advisory.
- Update LoginPress Pro to version 6.2.4, or to a newer vendor-supported patched version from the official WordPress update channel.
- If the update cannot be applied immediately, disable LoginPress Pro or the affected feature and restrict access with roles, authentication, WAF rules, or temporary route blocking.
- Review affected REST endpoints, AJAX actions, roles, capabilities, account changes, orders, bookings, payments, and admin actions for unauthorized activity.
- Rotate administrator sessions, API keys, webhook secrets, payment or integration tokens, and affected credentials if logs or content review suggest compromise.
- Clear WordPress, object, CDN, page-builder, security plugin, and browser caches after patching so vulnerable assets or stored payloads are not served.

Verify the fix
- Confirm the running LoginPress Pro version is version 6.2.4 or newer, and record the patched version in the remediation ticket.
- Verify unauthenticated or low-privilege users can no longer trigger the affected action, endpoint, account, payment, booking, or settings change.
- Review web server, WordPress, security plugin, WAF, database, and application logs for exploitation attempts before and after the fix.
- Retest normal visitor, subscriber, customer, editor, administrator, checkout, form, API, booking, or integration workflows to confirm expected behavior still works.
- Run a fresh Fixnx scan and document the public exposure state, patched version, log review, and any cleanup evidence.
