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 · unedited
Deserialization of Untrusted Data vulnerability in Repute Infosystems ARMember.This issue affects ARMember: from n/a through 4.0.26.

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 · moderate confidence

A deserialization of untrusted data vulnerability exists in ARMember plugin versions up to 4.0.26. This class of vulnerability occurs when application accepts and deserializes data from untrusted sources without proper validation, potentially allowing attackers to manipulate serialized objects to execute arbitrary code or conduct other attacks.

MitigationUpdate ARMember to the latest version (4.0.27 or later) which presumably contains the security fix. If immediate update is not possible, restrict access to affected endpoints and monitor for suspicious serialized data patterns.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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. Verify ARMember plugin is installed
    Check the WordPress plugins directory (wp-content/plugins) for the armember folder, or query the WordPress database: SELECT option_value FROM wp_options WHERE option_name = 'active_plugins'
    Affected if ARMember folder exists in plugins directory or is in the active plugins list
  2. Determine installed ARMember version
    Read the version from the main plugin file (wp-content/plugins/armember/armember.php) in the plugin header comment, or check WordPress admin under Plugins > Installed Plugins
    Affected if Version displayed is less than 4.0.27 (e.g., 4.0.26, 4.0.25, etc.)
  3. Identify deserialization endpoints
    Search plugin files for unserialize() calls: grep -r 'unserialize' wp-content/plugins/armember/
    Affected if Code contains unserialize() calls processing external input (e.g., $_POST, $_GET, $_REQUEST)
  4. Check for publicly accessible handler files
    Review plugin directory for PHP files that handle serialized data submissions, typically in AJAX handlers or form processing files accessible via admin-ajax.php or front-end endpoints
    Affected if Handler files accept and process serialized data from unauthenticated or authenticated users

You are affected if ARMember plugin version is below 4.0.27 and the plugin's deserialization functionality processes untrusted input from user requests.

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.

dbcve · scoped
Upgrade available Upgrade to 4.0.27 or later
Fixed in 4.0.27
Interim mitigation

Update ARMember to the latest version (4.0.27 or later) which presumably contains the security fix. If immediate update is not possible, restrict access to affected endpoints and monitor for suspicious serialized data patterns.

Recommended fix High confidence

ARMember version 4.0.27

  1. 1. Back up your WordPress site and database before making any changes
  2. 2. Navigate to Plugins > Installed Plugins in your WordPress admin dashboard
  3. 3. Find ARMember in the plugin list
  4. 4. If an update to version 4.0.27 or higher is available, click 'Update Now' to install the fixed version
  5. 5. Alternatively, download ARMember version 4.0.27 or latest from the official WordPress repository or vendor
  6. 6. Deactivate the current ARMember plugin, then delete it, then upload and activate the new version
  7. 7. Verify the plugin is running version 4.0.27 or higher under Plugins > Installed Plugins
  8. 8. Test critical membership flows (registration, login, content access) to ensure functionality
