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 Marcus (aka @msykes) Events Manager events-manager allows Object Injection.This issue affects Events Manager: from n/a through <= 7.3.6.

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

The Events Manager WordPress plugin (versions <= 7.3.6) is vulnerable to PHP Object Injection via unsafe deserialization of untrusted data. An attacker can potentially inject malicious PHP objects into the application, which may lead to remote code execution if certain magic methods (such as __wakeup or __destruct) exist within the plugin or other installed plugins/themes.

MitigationUpdate Events Manager to the latest version. If patching is not immediately possible, disable the plugin until an update is available. Additionally, ensure all other plugins and themes are kept up to date to minimize the risk from chained object injection attacks.

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. Confirm Events Manager plugin is installed
    In WordPress admin, navigate to Plugins and locate Events Manager in the list of installed plugins
    Affected if Events Manager plugin appears in the WordPress installation
  2. Identify installed version of Events Manager
    In WordPress admin > Plugins, find Events Manager and read the version number displayed beneath the plugin name
    Affected if Version is 7.3.6 or lower (the vulnerable range)
  3. Verify plugin is active
    In WordPress admin > Plugins, check that Events Manager status shows as Active rather than Deactivated
    Affected if Plugin is currently activated and can process requests containing untrusted data
  4. Audit other plugins for deserialization gadget chains
    Review installed plugins and themes for classes containing __wakeup, __destruct, or other magic methods that could be triggered during PHP object deserialization
    Affected if Additional plugins or themes with exploitable magic methods are present in the installation

Environment is affected if Events Manager version 7.3.6 or lower is installed and active, with elevated risk when other plugins contain deserialization gadget chains that could enable remote code execution

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

Update Events Manager to the latest version. If patching is not immediately possible, disable the plugin until an update is available. Additionally, ensure all other plugins and themes are kept up to date to minimize the risk from chained object injection attacks.

Recommended fix Moderate confidence

Events Manager 7.3.7 or later

  1. 1. Navigate to the WordPress admin dashboard for the site using the Events Manager plugin.
  2. 2. Go to Plugins > Installed Plugins.
  3. 3. Locate the Events Manager plugin in the list.
  4. 4. If an update is available, click 'Update Now' to upgrade to the latest version.
  5. 5. If no update appears, manually download the latest version from the official WordPress plugin repository (wordpress.org/plugins/events-manager/) and reinstall.
  6. 6. After updating, clear any site caches and verify the plugin is functioning correctly.
Caveat Review plugin settings after upgrade as minor configuration changes may occur in feature releases
