CVE-2025-7713
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 (XSS or 'Cross-site Scripting') vulnerability in Global Interactive Design Media Software Inc. Content Management System (CMS) allows XSS Through HTTP Headers. This issue affects Content Management System (CMS): through 21072025.
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 confidenceThe CMS fails to properly sanitize HTTP header inputs before using them in web page generation, allowing attackers to inject malicious JavaScript that gets stored and executed in the browsers of users who view the affected content.

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.
-
Confirm Globalmedya CMS installationCheck your web server for the presence of Globalmedya CMS files or check the application version information typically found in admin panels, README files, or version detection endpointsAffected if Globalmedya Content Management System is present and version is 2025-07-21 or earlier
-
Identify HTTP header usage in the applicationReview application source code or configuration to identify where HTTP headers (such as User-Agent, Referer, X-Forwarded-For, or custom headers) are collected and used in page generationAffected if The application processes and incorporates HTTP header values into web pages without sanitization
-
Check for stored content functionalityIdentify if the application has features that store and display user-contributed content (comments, posts, user profiles, or admin-modified fields) that could contain header-derived dataAffected if Stored content functionality exists that renders header-derived values to users
-
Test for XSS via HTTP headers (safe check)Send a benign test value (such as a harmless alphanumeric string) in an HTTP header and monitor if that value appears in the rendered page without modificationAffected if Header values are reflected in output without encoding or sanitization applied
You are affected if Globalmedya CMS version 2025-07-21 or earlier is installed AND the application stores or displays HTTP header values in web pages without proper output 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.
From vendor dataImplement strict input validation and output encoding for all HTTP header data before it's rendered in web pages. All header-derived values should be treated as untrusted and escaped before output.
