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
WebBoss.io CMS before v3.7.0.1 was discovered to contain a reflected cross-site scripting (XSS) vulnerability.

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

WebBoss.io CMS versions prior to 3.7.0.1 contain a reflected cross-site scripting (XSS) vulnerability. This occurs when user-supplied input is improperly validated or sanitized before being reflected back in the application's response, allowing attackers to inject malicious scripts that execute in the victim's browser.

MitigationUpgrade WebBoss.io CMS to version 3.7.0.1 or later. Additionally, implement proper input validation, output encoding, and content security policy headers to prevent XSS attacks.

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. Identify WebBoss.io CMS version
    Locate the version number in the application admin panel, footer of rendered pages, or in a version/configuration file within the webroot. Check files such as version.php, config.php, or the login/admin interface for a version display.
    Affected if The discovered version is any release prior to 3.7.0.1 (e.g., 3.6.x, 3.5.x, older).
  2. Confirm WebBoss.io installation
    Verify the application is WebBoss.io CMS by examining the page source for 'webboss' branding, checking the HTML title tag, or reviewing built-in path structures such as /admin/, /cms/, or similar WebBoss-specific directories.
    Affected if The application is confirmed as WebBoss.io CMS.
  3. Identify user input reflection points
    Review application URLs and forms that accept user-supplied data, such as search parameters, query strings, form inputs, and error message displays. Examine URL parameters in the browser address bar and inspect the response when submitting test values.
    Affected if User-supplied input from URL parameters or form fields is reflected back in the application's response without visible sanitization or encoding.
  4. Check for content security policy
    Inspect the HTTP response headers for the presence of Content-Security-Policy (CSP) header, particularly the 'script-src' directive. This can be done via browser developer tools, curl -I command, or checking server configuration.
    Affected if No CSP header is set, or the CSP allows inline scripts, which would enable reflected XSS to execute.

You are affected if WebBoss.io CMS is installed and the version is below 3.7.0.1, with user input being reflected in responses without sanitization and without protective CSP headers.

Upgrade available Upgrade to 3.7.0.1 or later
Fixed in 3.7.0.1
Interim mitigation

Upgrade WebBoss.io CMS to version 3.7.0.1 or later. Additionally, implement proper input validation, output encoding, and content security policy headers to prevent XSS attacks.

Recommended fix Moderate confidence

WebBoss.io CMS v3.7.0.1

  1. 1. Back up your current WebBoss.io CMS installation and database before proceeding with any upgrade.
  2. 2. Download the latest stable version of WebBoss.io CMS v3.7.0.1 from the official source (webboss.io) or your licensed distribution channel.
  3. 3. Review the upgrade documentation provided with v3.7.0.1 for any specific migration or pre-upgrade requirements.
  4. 4. Execute the upgrade process according to the official upgrade instructions (typically involves replacing CMS files while preserving configuration and content).
  5. 5. Verify the upgrade was successful by checking the CMS version in the admin panel.
  6. 6. Test the application functionality to ensure normal operation after the upgrade.
  7. 7. Validate that the XSS vulnerability is remediated by confirming the fix is applied.
