What is CVE-2026-76975?
CVE-2026-76975 is a medium-severity cross-site scripting vulnerability in SAP_SE SAPUI5 (Support Assistant Overlay), published on 13 Oct 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official 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.
Weakness: CWE-79
