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 for WordPress has multiple XSS issues.

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 before version 5.5.7 contains multiple Cross-Site Scripting (XSS) vulnerabilities. XSS flaws allow attackers to inject malicious scripts into web pages viewed by other users, potentially leading to session hijacking, credential theft, or redirection to malicious sites. The medium severity rating indicates the vulnerability is exploitable but may require user interaction.

MitigationUpdate the events-manager plugin to version 5.5.7 or later. If immediate updating is not possible, disable the plugin temporarily and review recent admin activity logs for signs of exploitation.

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. Locate the Events Manager plugin
    In WordPress admin, go to Plugins > Installed Plugins. Look for 'Events Manager' or 'Pixelite Events Manager' in the list of installed plugins.
    Affected if Plugin is not found in the installed plugins list (not applicable)
  2. Verify the installed version
    In the Plugins list page, find the Events Manager plugin entry. The version number is displayed beneath the plugin name. Alternatively, check the plugin main file header in wp-content/plugins/events-manager/events-manager.php for the 'Version' comment.
    Affected if Version number displayed is less than 5.5.7 (e.g., 5.5.6, 5.5.5, etc.)
  3. Confirm the plugin is active
    In Plugins > Installed Plugins, check if Events Manager shows 'Active' status under the plugin name. An inactive plugin with a vulnerable version would not be directly exploitable.
    Affected if Plugin version is below 5.5.7 AND the plugin status is Active

You are affected if the Events Manager plugin is installed with a version lower than 5.5.7 and the plugin is currently active on your WordPress site.
