Official description
SAPUI5 allows a key user with content adaptation privileges to inject malicious script content into persisted application changes.

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.
