CVE-2026-25353
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 · uneditedImproper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in skygroup Nooni nooni allows Reflected XSS.This issue affects Nooni: from n/a through < 1.5.1.
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 confidenceThis is a reflected cross-site scripting (XSS) vulnerability in the Nooni web application (versions before 1.5.1). The application fails to properly neutralize user-supplied input before embedding it in web pages, allowing attackers to inject malicious scripts that execute in the context of victim users' browsers.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify Nooni application versionCheck the application's admin dashboard, footer, or version file (commonly version.php, package.json, or similar manifest files in the web root) for the installed version numberAffected if The version is lower than 1.5.1 (e.g., 1.5.0, 1.4.x, or any pre-1.5.1 release)
-
Locate user input fieldsReview application forms, search boxes, URL parameters, and any endpoint that accepts user-supplied data and returns it in the HTTP responseAffected if The application reflects user input back into the rendered HTML without visible encoding
-
Inspect HTTP response headersCapture an HTTP response using browser dev tools or a proxy (e.g., Burp, OWASP ZAP) and examine the Content-Type and any X-XSS-Protection headerAffected if The application lacks security headers such as X-XSS-Protection or Content-Security-Policy
-
Test for reflected input in URLsSubmit a benign test payload (e.g., <script>alert(1)</script> or <img src=x onerror=alert(1)>) in a URL parameter and observe if the payload appears unescaped in the response bodyAffected if The payload is rendered as-is in the page source without HTML entity encoding (e.g., <script> appears as <script>)
You are affected if the installed Nooni version is below 1.5.1 AND user-supplied input is reflected in web pages without proper HTML encoding.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedImplement proper input validation and output encoding/escaping for all user-supplied data before rendering it in web pages. Consider using a content security policy (CSP) as an additional defense-in-depth measure.
Nooni theme version 1.5.1 or later
- 1. Backup your current Nooni theme and website data before performing any updates
- 2. Navigate to your WordPress dashboard → Appearance → Themes
- 3. Check if version 1.5.1 or later is available in the theme repository or from your theme provider
- 4. Update Nooni theme to version 1.5.1 or the latest available version
- 5. After updating, clear any caching mechanisms (site cache, CDN cache, browser cache)
- 6. Test the affected pages/endpoints to verify the XSS vulnerability is resolved
- 7. Monitor for any console errors or unexpected behavior post-update
