- CVE-2025-13737, 28 Nov 2025
- The Nextend Social Login and Register plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.1.21. This is due to missing or incorrect nonce validation on the 'unlinkUser' function. This makes it possible for unauthenticated attackers to unlink the user's social login via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. CVE record
- CVE-2024-9893, 16 Oct 2024
- The Nextend Social Login Pro plugin for WordPress is vulnerable to authentication bypass in all versions up to, and including, 3.1.14. This is due to insufficient verification on the user being returned by the social login token. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to the email and the user does not have an already-existing account for the service returning the token. CVE record
- CVE-2024-1775, 2 Mar 2024
- The Nextend Social Login and Register plugin for WordPress is vulnerable to a self-based Reflected Cross-Site Scripting via the ‘error_description’ parameter in all versions up to, and including, 3.1.12 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers, with access to a subscriber-level account, to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. NOTE: This vulnerability can be successfully exploited on a vulnerable WordPress instance against an OAuth pre-authenticated higher-level user (e.g., administrator) by leveraging a cross-site request forgery in conjunction with a certain social engineering technique to achieve a critical impact scenario (cross-site scripting to administrator-level account creation). However, successful exploitation requires "Debug mode" to be enabled in the plugin's "Global Settings". CVE record
