Advisory
On 13.01.2026 a security relevant correction has been released by SAP SE. The manufacturer resolves an issue within SAP Business Connector.
SAP Note 3666061 addresses "[CVE-2026-0514] Cross-Site Scripting (XSS) vulnerability in SAP Business Connector" to prevent cross-site scripting (xss) with a medium risk for exploitation.
A workaround does not exist, according to SAP Security Advisory team. It is advisable to implement the correction as part of maintenance, the team suggests.
Cross-site scripting (XSS) is the name of a class of security vulnerabilities that can occur in web-based
applications. XSS combines
all vulnerabilities that allow an attacker to inject HTML Markup and/or JavaScript into the front end of the
affected web application.
XSS attacks can occur whenever the application dynamically creates its HTML/JavaScript/CSS content, which is passed
to the
user's web browser, and attacker-controlled values are used in this process. If these values are included in the
generated code without proper validation and encoding, the attacker is able to include arbitrary
coding snippets into the application's front end. The code is then rendered by the victim's web browser and
interpreted in the victim's current authentication context.
Risk specification
SAP Business Connector allows an unauthenticated attacker to craft a malicious link that, when clicked by a user, can lead to the execution of attacker-controlled scripts, resulting in unauthorized modification or exposure of web client data.
Solution
Previously unprotected areas now correctly encode input to prevent XSS attacks.
