CVE-2026-25442
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 QantumThemes Kentha kentha allows Reflected XSS.This issue affects Kentha: from n/a through <= 4.7.2.
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 confidenceReflected XSS vulnerability in QantumThemes Kentha theme allows attackers to inject malicious JavaScript through unsanitized user input that gets reflected in web pages without proper output encoding. This occurs in the web page generation process where user-supplied data is directly included in the HTML response.

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 Kentha theme installationInspect the theme files or check the theme version through the theme's main style.css or version file typically found in /wp-content/themes/kentha/ directoryAffected if Kentha theme by QantumThemes is present in the WordPress themes folder
-
Locate theme version informationOpen the style.css file in the Kentha theme directory and look for the 'Version:' comment header, or check any version.php or readme.txt file included with the themeAffected if The installed version cannot be verified or is within an affected range (older versions without XSS fix)
-
Identify user input reflection pointsReview the theme's PHP files for code that uses $_GET, $_POST, or $_REQUEST parameters directly in HTML output without sanitization functions like htmlspecialchars() or esc_html()Affected if User-supplied parameters from HTTP requests are found being output directly into page HTML without encoding
-
Test for reflected XSS vulnerabilitySubmit a test payload containing a benign XSS probe (such as <script>alert('XSS')</script> or similar) as a URL parameter and examine if the payload is reflected unescaped in the page sourceAffected if The injected payload appears in the HTML response without being HTML-encoded or sanitized
-
Verify Content Security Policy headerCheck the HTTP response headers for Content-Security-Policy or X-Content-Security-Policy headers that could mitigate XSS exploitationAffected if No CSP headers are present and user input is reflected without encoding
If the Kentha theme is installed and any user-supplied input parameters are being reflected in web pages without HTML encoding or sanitization, the environment is affected by this reflected XSS vulnerability.

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.
From vendor dataApply context-aware output encoding and implement input validation for all user-supplied parameters before reflecting them in page content. Additionally, deploy Content Security Policy (CSP) headers as a defense-in-depth measure.
