Vulnerability from github – Published: 2026-08-11 03:31 – Updated: 2026-08-11 03:31

Details

SAPUI5 allows a key user with content adaptation privileges to inject malicious script content into persisted application changes. When another user subsequently opens the adapted application, the injected script executes in the victim's browser session. Successful exploitation could allow the attacker to access sensitive session data and perform unauthorized actions on behalf of the victim, resulting in a high impact on confidentiality and integrity. There is no impact on availability.

Severity

6.1 (Medium)
