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 Photos and Files Contest Gallery WordPress plugin before 21.3.1 does not sanitize and escape some parameters, which could allow users with a role as low as author to perform Cross-Site Scripting attacks.

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 Photos and Files Contest Gallery WordPress plugin before version 21.3.1 fails to properly sanitize and escape certain input parameters, enabling authenticated Cross-Site Scripting (XSS) attacks. Users with author-level permissions or higher can inject malicious scripts that execute in the browsers of other users viewing the affected plugin pages.

MitigationUpdate the Photos and Files Contest Gallery plugin to version 21.3.1 or later, which includes proper input sanitization and output escaping for the affected parameters.

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. Check the installed Contest Gallery plugin version

    Affected if The plugin is active and running a version below 21.3.1
  3. Confirm presence of users with author-level or higher privileges
    In WordPress admin, go to Users > All Users and review the role column. Check if any users have the 'Author', 'Editor', or 'Administrator' role assigned.
    Affected if There are users with author-level permissions or higher, as these roles can trigger the vulnerable code paths
  4. Identify access to plugin admin pages
