CVE-2026-1994
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe s2Member WordPress plugin versions up to 260127 lacks proper identity validation in its password reset/change functionality, allowing unauthenticated attackers to supply arbitrary user identifiers and new passwords, effectively taking over any account including administrators.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify s2Member plugin is installedNavigate to WordPress admin dashboard > Plugins > Installed Plugins, or check the /wp-content/plugins/ directory for the s2member folderAffected if The s2Member plugin exists in the plugins directory or is listed in the WordPress admin
-
Identify installed s2Member versionIn WordPress admin, go to Plugins > Installed Plugins and locate s2Member to see the version number. Alternatively, check the main plugin file header in /wp-content/plugins/s2member/s2member.php for the 'Version' tagAffected if The installed version is at or below the vulnerable version range (prior to the fix released around January 26, 2026)
-
Check if password reset endpoints are accessibleTest the s2Member password reset API endpoint by sending a POST request to the site's XMLRPC or REST API endpoint for s2Member (commonly /?s2member_paypal_notify=1 or XMLRPC), or check the plugin's configuration for password reset functionality enabled statusAffected if The password reset functionality is enabled and accepts unauthenticated requests
-
Verify WordPress user roles at riskCheck WordPress Users > All Users for accounts with Administrator role. These accounts would be targetable via this vulnerability if s2Member's password reset is vulnerableAffected if Any administrative or high-privilege user accounts exist on the WordPress site with s2Member installed
Your environment is affected if s2Member is installed with a version prior to the fixed release (beyond 260127) and the plugin's password reset functionality is accessible to unauthenticated users.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate s2Member to the latest patched version immediately. If no patch is available, disable the plugin or implement web application firewall rules to block unauthorized password change requests.
