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 PickPlugins Accordion accordions allows Object Injection.This issue affects Accordion: from n/a through <= 2.3.11.

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

This is a PHP Object Injection vulnerability in the PickPlugins Accordion WordPress plugin (versions <= 2.3.11). The plugin uses unsafe PHP unserialize() on untrusted data, allowing attackers to craft malicious serialized PHP objects. With suitable 'gadget chains' (available classes in the WordPress environment), this can lead to remote code execution.

MitigationUpdate the PickPlugins Accordion plugin to the latest patched version immediately. If no update is available, deactivate the plugin until a fix is released. The remediation involves replacing unsafe unserialize() calls with json_decode() or other safe deserialization methods.

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. Identify if PickPlugins Accordion plugin is installed
    Check the WordPress plugins directory (wp-content/plugins/) for a folder named 'pickplugins-accordion' or similar accordion-related plugin folders. You can also list installed plugins via WP-CLI: wp plugin list --name=accordion
    Affected if The plugin folder 'pickplugins-accordion' exists in the plugins directory
  2. Determine the installed version of the plugin
    Open the main plugin file (usually pickplugins-accordion.php) and locate the version comment in the file header, or check the readme.txt file for the 'Stable tag' entry. Compare the version number to 2.3.11
    Affected if The installed version is 2.3.11 or any version lower than 2.3.11
  3. Verify the plugin is active
    Check if the plugin is enabled by examining the wp_options table for the 'active_plugins' option, or use WP-CLI: wp plugin status pickplugins-accordion
    Affected if The plugin shows as 'Active' in the WordPress admin or via WP-CLI status command
  4. Identify the vulnerable unserialize() call source
    Search the plugin files for 'unserialize(' function calls, particularly in files that handle user input or AJAX endpoints. Check PHP files in the plugin root and includes subdirectories. Look for unserialize() calls processing $_POST, $_GET, or $_REQUEST superglobals
    Affected if The plugin code contains an unserialize() call that processes untrusted input from request parameters

Your environment is affected if the PickPlugins Accordion plugin version is 2.3.11 or lower AND the plugin is currently active, as this enables the deserialization vulnerability to be exploited by authenticated attackers.
