NVD · unedited
Deserialization of Untrusted Data vulnerability in taketin TAKETIN To WP Membership taketin-to-wp-membership allows Object Injection.This issue affects TAKETIN To WP Membership: from n/a through <= 2.8.17.

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 confidence

The TAKETIN To WP Membership WordPress plugin (versions <= 2.8.17) is vulnerable to PHP Object Injection via deserialization of untrusted data. An attacker can craft malicious serialized PHP objects and inject them through user-controllable input that gets deserialized without proper validation, potentially leading to remote code execution if POP (Property Oriented Programming) chains exist.

MitigationUpdate the plugin to the latest version which should contain a patch for the deserialization vulnerability, or implement strict validation to ensure only expected, whitelisted data types are deserialized.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check the plugin version
    Navigate to WordPress admin > Plugins > Installed Plugins > TAKETIN To WP Membership, or read the plugin's main PHP file header (typically named taketin-wp-membership.php or similar in wp-content/plugins/taketin-wp-membership/) to find the 'Version' field
    Affected if The installed version is 2.8.17 or lower
  2. Locate deserialization code in the plugin
    Search all PHP files in the plugin directory for 'unserialize' function calls. Use grep, a code editor search, or manually review files that handle form submissions, API endpoints, or AJAX requests
    Affected if Code containing unserialize() is found that processes input without prior sanitization
  3. Identify user-controllable input sources
    Examine the deserialized code paths to determine if $_GET, $_POST, $_REQUEST, or similar superglobals are passed to unserialize() without validation
    Affected if User-supplied data from request parameters flows directly into unserialize() calls
  4. Review plugin settings for exposed endpoints
    Check WordPress admin > Settings > TAKETIN To WP Membership (or equivalent) for any exposed API endpoints, public forms, or AJAX actions that could be reachable by unauthenticated users
    Affected if The plugin exposes endpoints accessible to visitors or low-privilege users that trigger the vulnerable deserialization

A user is affected if the TAKETIN To WP Membership plugin version is 2.8.17 or lower AND the plugin contains code that deserializes user-supplied input without validation, particularly on publicly accessible endpoints.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update the plugin to the latest version which should contain a patch for the deserialization vulnerability, or implement strict validation to ensure only expected, whitelisted data types are deserialized.

Recommended fix Moderate confidence

Version 2.8.18 or later (latest available version)

  1. 1. Log in to the WordPress admin dashboard
  2. 2. Navigate to Plugins > Installed Plugins
  3. 3. Locate TAKETIN To WP Membership plugin
  4. 4. If an update is available, click 'Update Now' to upgrade to the latest version
  5. 5. Verify the update completes successfully
  6. 6. Test the membership functionality to ensure the plugin is working correctly after update
