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 Better Find and Replace – AI-Powered Suggestions plugin for WordPress is vulnerable to Stored Cross-Site Scripting via uploaded image title in versions up to, and including, 1.7.9 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

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

The Better Find and Replace WordPress plugin fails to properly sanitize and escape image titles during upload, allowing authenticated users with author-level access or higher to inject malicious JavaScript that executes in the browsers of users viewing affected pages.

MitigationUpdate the plugin to a version newer than 1.7.9 once available, or implement proper input sanitization (sanitize_text_field) and output escaping (esc_html/esc_attr) on image title fields.

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 the plugin is installed
    Navigate to WordPress admin > Plugins and locate 'Better Find and Replace' in the list of installed plugins
    Affected if The plugin is installed and active
  2. Check the plugin version
    In the Plugins list, click on 'Better Find and Replace' to view the plugin details and note the installed version number
    Affected if The installed version is 1.7.9 or lower
  3. Confirm author-level or higher users exist
    Go to Users > All Users in the WordPress admin and check if any users have the role of Author, Editor, or Administrator
    Affected if At least one user with Author role or higher exists in the system
  4. Inspect media library for custom image titles
    Go to Media > Library, view uploaded images, and check the 'Title' field for each image to see if any contain custom titles (as opposed to default auto-generated filenames)
    Affected if Images with custom titles are present in the media library and those titles are displayed on pages viewable by other users

The environment is affected if the Better Find and Replace plugin version is 1.7.9 or lower, the plugin is active, author-level users exist, and images with custom titles are stored in the media library.
