Executive Summary

CVE-2026-34951 is a reflected cross-site scripting (XSS) vulnerability in the Workbench PHP package used to interact with Salesforce.com organizations. It occurs because the footerScripts parameter does not properly sanitize user-supplied input before rendering it in the page response.

This improper neutralization allows attackers to inject malicious scripts that execute in the context of a victim's browser, particularly targeting error pages.

The vulnerability affects all versions up to and including 53.0.0 and has been fixed in version 65.0.0.

Detection Guidance

This vulnerability is a reflected cross-site scripting (XSS) issue involving the footerScripts parameter in Workbench versions up to 53.0.0. Detection involves testing if the footerScripts parameter improperly sanitizes input and reflects it in the page response.

A common method to detect reflected XSS vulnerabilities is to send a crafted HTTP request with a benign script payload in the footerScripts parameter and observe if it is executed or reflected unsanitized in the response.

For example, you can use curl or similar tools to send a request like:

• curl -v "http://[target]/footer.php?footerScripts=<script>alert('XSS')</script>"

If the response contains the script tag unescaped or the script executes in a browser, the vulnerability is present.

Mitigation Strategies

The primary mitigation step is to upgrade Workbench to version 65.0.0 or later, where this reflected XSS vulnerability has been fixed.

Until the upgrade can be performed, users should avoid interacting with untrusted input in the footerScripts parameter and consider restricting access to the affected Workbench versions.

Additionally, applying web application firewall (WAF) rules to detect and block suspicious scripts in requests targeting the footerScripts parameter can help reduce risk.
