CVE-2025-54783
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 · uneditedSuiteCRM is an open-source, enterprise-ready Customer Relationship Management (CRM) software application. Versions 7.14.6 and below have a Reflected Cross-Site Scripting (XSS) vulnerability. This vulnerability allows an attacker to execute JavaScript code by modifying the HTTP Referer header to include some arbitrary domain with malicious JavaScript code at the end. The server will attempt to block the arbitrary domain but allow the JavaScript code to execute. This is fixed in version 7.14.7.
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 confidenceSuiteCRM versions 7.14.6 and below contain a reflected XSS vulnerability where the HTTP Referer header is not properly sanitized. Attackers can inject malicious JavaScript code by modifying the Referer header to include an arbitrary domain followed by malicious script content, which the server fails to block.

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.
-
Check installed SuiteCRM versionLocate the SuiteCRM version by viewing the file at ./suitecrm_version.php, or log into the admin panel and navigate to Admin > About SuiteCRM to view the version number.Affected if The version displayed is 7.14.6 or below, meaning it is earlier than the fixed version 7.14.7
-
Identify if Referer header is reflected in responsesReview application responses for any reflection of the HTTP Referer header. This can be done by sending a request with a crafted Referer header (e.g., Referer: http://attacker.com/test) and examining if the value appears in the HTML response body without encoding.Affected if The Referer header value is reflected in any page output without proper HTML encoding or sanitization
-
Verify Referer header sanitization in source codeExamine the SuiteCRM source code for how the Referer header is handled. Search for $_SERVER['HTTP_REFERER'] or $_SERVER['REFERRER'] in the codebase, particularly in files under the /include/ or /MVC/ directories.Affected if The code retrieves the Referer header and outputs it directly to the response without applying htmlspecialchars() or equivalent encoding functions
You are affected if your SuiteCRM installation is version 7.14.6 or below AND any part of your application reflects the HTTP Referer header in its response without sanitization.

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 · scoped7.14.7
