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
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Visualmodo Borderless borderless allows Cross-Site Scripting (XSS).This issue affects Borderless: from n/a through <= 1.5.8.

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 stored Cross-Site Scripting (XSS) vulnerability exists in the Visualmodo Borderless WordPress theme (versions up to 1.5.8). The vulnerability stems from improper input neutralization during web page generation, allowing attackers to inject malicious scripts that execute in the browsers of users viewing affected content.

MitigationUpdate the Borderless theme to the latest patched version. Until then, implement output encoding/sanitization on user-supplied input fields and consider adding a Content Security Policy (CSP) header to mitigate XSS execution.

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 Borderless theme version
    In WordPress admin, go to Appearance > Themes and click on the Borderless theme to view its details. Alternatively, inspect the style.css file in wp-content/themes/borderless/ and look for the 'Version:' header.
    Affected if Version is 1.5.8 or lower (versions below 1.5.9 are affected)
  2. Identify user input points in theme
    Review the theme files for any frontend forms, comment fields, or content display areas that accept and render user-supplied data. Check template files (*.php) in the theme directory for functions that output dynamic content without sanitization functions like esc_html(), esc_attr(), or wp_kses().
    Affected if Theme outputs user-provided content without proper sanitization functions
  3. Inspect theme customizer and widget areas
    Navigate to WordPress admin > Appearance > Customize and examine any Borderless-specific panels, widget areas, or theme options that accept text input from users. Also check Appearance > Widgets for any Borderless widgets handling user text.
    Affected if Theme customizer or widget areas accept and display unsanitized user input
  4. Review AJAX and API endpoints
    Examine the theme's AJAX handlers (typically in functions.php or separate handler files) that process user submissions. Look for any endpoints that accept user input and return it to the frontend without using functions like sanitize_text_field() or esc_html().
    Affected if Theme contains AJAX/API handlers that process and display user input insecurely

If the Borderless theme version is below 1.5.9 AND the site has user-contributed content displayed through theme templates, the installation is likely vulnerable to stored XSS.

Upgrade available Upgrade to 1.5.9 or later
Fixed in 1.5.9
Interim mitigation

Update the Borderless theme to the latest patched version. Until then, implement output encoding/sanitization on user-supplied input fields and consider adding a Content Security Policy (CSP) header to mitigate XSS execution.

Recommended fix High confidence

Borderless version 1.5.9

  1. Backup your WordPress site before performing any updates
