LoginPress Pro <= 6.2.3 - Unauthenticated Authentication Bypass via Unverified OAuth Email via GitHub OAuth Callback
The LoginPress Pro plugin for WordPress is vulnerable to Authentication Bypass via the GitHub OAuth callback in versions up to, and including, 6.2.3. The vulnerability exists in the loginpress_on_github_login() function, which blindly trusts the first element (profile[0]['email']) of the array returned by GitHub's /user/emails endpoint as an account-binding identifier without verifying that the email carries a verified === true status. This makes it possible for unauthenticated attackers to log in as any existing WordPress user, including administrators, by adding an unverified email address matching a local account to their GitHub profile and triggering the OAuth callback via a crafted code parameter — causing the plugin to call get_user_by('email', ...) and establish an authenticated session for the matched account. Practical exploitation is conditional on GitHub returning the attacker-added unverified email at index 0 of the /user/emails response, as GitHub typically prioritizes the primary verified address first; nonetheless, the absence of any email verification check in the plugin constitutes a fundamental authentication bypass flaw.
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-2026-12597, 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, support, booking, import/export, page-builder, 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, WooCommerce, support, booking, and content-management 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, tickets, marketplace actions, 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, WooCommerce, booking/support 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, ticket, import/export, snippet, or settings change.
- Review web server, WordPress, security plugin, WAF, database, WooCommerce, booking/support, and application logs for exploitation attempts before and after the fix.
- Retest normal visitor, subscriber, customer, editor, administrator, checkout, form, API, booking, support ticket, import/export, backup/restore, snippet, 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.
