CVE-2024-0899
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.

This makes it possible for unauthenticated attackers to see the contents of those posts and pages.
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.

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.
-
Confirm s2Member plugin installationNavigate to WordPress Admin > Plugins and locate s2Member in the installed plugins list, or check the plugin files in /wp-content/plugins/ for the s2member directory and review the main plugin file header for the version numberAffected if s2Member plugin is not installed on the WordPress site
-
Identify installed s2Member versionIn WordPress Admin > Plugins, click on the s2Member plugin to view its details and note the version number displayed, or inspect the plugin's main PHP file (such as s2member.php) and look for the 'Version' header commentAffected if The version is 230815 or any version prior to it (versions up to and including 230815 are vulnerable)
-
Verify content restriction is configuredCheck s2Member settings in WordPress Admin under s2Member > Restriction Options, or review page/post visibility settings to confirm the site uses s2Member to restrict content to members onlyAffected if The site actively restricts content to members-only using s2Member's protection features
-
Confirm API accessibilityTest access to s2Member API endpoints without authentication (typically found at /?s2member_, /?s2member_, or /wp-json/s2member/ paths) by attempting to retrieve protected content via browser or curl request while logged outAffected if The API endpoint responds to unauthenticated requests and returns protected content that should require authentication
A user is affected if s2Member plugin version 230815 or earlier is installed, content restriction to members is enabled, and the API endpoint is accessible without authentication, allowing unauthorized access to protected posts and pages.

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 the s2Member plugin to the latest version beyond 230815 to patch the API information exposure. If no update is available, temporarily disable the plugin's API endpoint or implement firewall rules to restrict unauthenticated access to the vulnerable API path.
