- CVE-2026-19804, 25 Sep 2026
- The s2Member - Excellent for All Kinds of Memberships, Content Restriction Paywalls & Member Access Subscriptions plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 260814 via the 'first_name' parameter parameter. This is due to insufficient sanitization of the first_name parameter via esc_refs(), which strips only regex backreferences and not PHP tags, before substitution into the eval'd Signup Tracking Codes template, combined with disclosure of the site-global proxy verification key that allows PayPal postback verification to be bypassed. This makes it possible for unauthenticated attackers to execute code on the server. Successful exploitation requires that the site administrator has configured a Signup Tracking Codes template containing the %%first_name%% placeholder (a documented, GUI-supported feature) and that the attacker has obtained the site-global proxy verification key, which is exposed in plaintext in the JSON response of any PayPal Checkout AJAX request on the target site. CVE record
- CVE-2026-15047, 10 Aug 2026
- The s2Member WordPress plugin before 260805 does not escape several shortcode attributes before outputting them inside an inline script context, allowing users with contributor-level access to inject arbitrary JavaScript that executes when a viewer opens the post (stored XSS). CVE record
- CVE-2026-1994, 19 Feb 2026
- The s2Member plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 260127. This is due to the plugin not properly validating a user's identity prior to updating their password. This makes it possible for unauthenticated attackers to change arbitrary user's passwords, including administrators, and leverage that to gain access to their account. CVE record
- CVE-2025-13732, 19 Feb 2026
- The s2Member - Excellent for All Kinds of Memberships, Content Restriction Paywalls & Member Access Subscriptions plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 's2Eot' shortcode in all versions up to, and including, 251005 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. CVE record
- CVE-2024-11376, 18 Feb 2025
- The s2Member - Excellent for All Kinds of Memberships, Content Restriction Paywalls & Member Access Subscriptions plugin for WordPress is vulnerable to Reflected Cross-Site Scripting due to the use of add_query_arg without appropriate escaping on the URL in all versions up to, and including, 241114. This makes it possible for unauthenticated attackers 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. CVE record
- CVE-2024-12562, 15 Feb 2025
- The s2Member Pro plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 241216 via deserialization of untrusted input from the 's2member_pro_remote_op' vulnerable parameter. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code. CVE record
- CVE-2024-8326, 17 Dec 2024
- The s2Member - Excellent for All Kinds of Memberships, Content Restriction Paywalls & Member Access Subscriptions plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 241114 via the 'sc_get_details' function. This makes it possible for authenticated attackers, with Contributor-level access and above, to extract sensitive data including user data and database configuration information, which can lead to reading, updating, or dropping database tables. The vulnerability was partially patched in version 241114. CVE record
