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
The events-manager plugin before 5.5.7.1 for WordPress has DOM XSS.

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

A DOM-based Cross-Site Scripting (XSS) vulnerability exists in the Events Manager WordPress plugin versions prior to 5.5.7.1. The vulnerability allows malicious JavaScript to be executed in a user's browser via the client-side (DOM) processing of user-supplied input without proper sanitization or encoding.

MitigationUpdate the Events Manager plugin to version 5.5.7.1 or later to patch the DOM XSS vulnerability. Until the update is applied, monitor for suspicious user activity and consider implementing Content Security Policy (CSP) headers as an additional defense-in-depth measure.

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 Events Manager plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and look for 'Events Manager' by Pixelite in the list. Note whether it is active or inactive.
    Affected if The plugin is installed and active
  2. Check the installed version number
    In the Plugins list, find the Events Manager entry and locate the version number displayed below the plugin name. Compare this against the affected range: versions prior to 5.5.7.1 are vulnerable.
    Affected if The installed version is below 5.5.7.1
  3. Identify DOM input handlers
    Inspect pages using Events Manager functionality (event submission forms, calendar displays, event lists). Look for client-side JavaScript that processes URL parameters, form inputs, or query strings without sanitization.
    Affected if User-supplied input is processed via JavaScript on the client side without proper encoding

If the Events Manager plugin version is installed and is lower than 5.5.7.1, the environment is affected by this DOM-based XSS vulnerability.
