Advisory
On 13.10.2026 a security relevant correction has been released by SAP SE. The manufacturer resolves an issue within SAP UI5.
SAP Note 3794572 addresses "3794572 - [CVE-2026-76975] Cross-Site Scripting (XSS) vulnerability in SAPUI5 (Support Assistant Overlay)" 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
SAPUI5 (Support Assistant Overlay) allows an unauthenticated attacker to craft a malicious link that, when accessed by a victim, causes client-side code to insert attacker-controlled input into the DOM without proper sanitization, allowing attacker-supplied scripts to execute in the victim's browser and resulting in unauthorized access to and modification of information within the victim's browser.
Solution
The affected URL parameter is now encoded to prevent DOM-based cross-site scripting.
