# CVE-2026-76975: Cross-Site Scripting (XSS) vulnerability in SAPUI5 (Support Assistant Overlay)

- Severity: CVSS 6.1 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Published: 2026-10-13 · Updated: 2026-10-13

## Affected

- SAP\_SE SAPUI5 (Support Assistant Overlay): SAP\_UI 754

## Description

Due to a DOM-Based Cross-Site Scripting (XSS) vulnerability, an unauthenticated attacker could generate a malicious link and make it publicly accessible. If an authenticated user accesses this link, client-side code reads the attacker-controlled input and writes it into the DOM without proper sanitization, causing attacker-supplied script to execute in the victim�s browser context. This could allow the attacker to access or modify information within the victim�s browser scope, impacting confidentiality and integrity, while availability remains unaffected.
