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 Live Composer Team Page Builder: Live Composer live-composer-page-builder.This issue affects Page Builder: Live Composer: from n/a through 1.5.25.

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 · low confidence

A deserialization of untrusted data vulnerability exists in the Live Composer Page Builder WordPress plugin (versions through 1.5.25). The vulnerability allows authenticated attackers (with contributor-level access or higher) to potentially execute arbitrary code by exploiting insecure deserialization of user-supplied data, likely through plugin settings or content imports.

MitigationUpdate to the latest patched version of Live Composer if available. If no patch exists, disable the plugin until a fix is released. Implement Web Application Firewall (WAF) rules to detect and block malicious serialized object payloads targeting the affected endpoint.

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 the plugin is installed
    Navigate to WordPress Admin > Plugins, or inspect the /wp-content/plugins/ directory for a folder named 'blueastral' or 'live-composer'
    Affected if The Blueastral Page Builder or Live Composer plugin is present on the system
  2. Check the installed version
    In WordPress Admin > Plugins, view the plugin details to see the version number, or read the main plugin file header in /wp-content/plugins/blueastral/ or /wp-content/plugins/live-composer/ for the 'Version' field
    Affected if The version number is 1.5.25 or lower
  3. Identify user roles with contributor access
    In WordPress Admin > Users, review the role assignment for each user. Contributors and higher roles (authors, editors, administrators) can exploit this vulnerability
    Affected if Any user account has contributor-level access or higher and the vulnerable plugin is installed
  4. Inspect plugin settings or content imports
    Review any custom content imports, theme options, or plugin settings that accept serialized data. Check server access logs for POST requests to plugin-related endpoints containing serialized object patterns
    Affected if Serialized PHP object patterns (like O:... or a:...) are present in plugin-related request data or stored settings
  5. Check for unauthorized code execution indicators
    Review the /wp-content/uploads/ directory for newly created PHP files, and check for unexpected administrator accounts or scheduled tasks in wp_options table
    Affected if Suspicious PHP files exist in uploads, or unauthorized admin accounts or cron jobs are present

A user is affected if the Blueastral/Live Composer Page Builder plugin version 1.5.25 or lower is installed AND at least one user account has contributor-level access or higher.

From vendor data
Upgrade available Upgrade to a release after 1.5.25
Interim mitigation

Update to the latest patched version of Live Composer if available. If no patch exists, disable the plugin until a fix is released. Implement Web Application Firewall (WAF) rules to detect and block malicious serialized object payloads targeting the affected endpoint.
