Title
Clickjacking vulnerability in SAPUI5(Frame Options Allowlist)
Summary
SAP UI5 does not sufficiently validate the parent frame's origin against the configured allowlist. An unauthenticated attacker could host a malicious page to bypass framing restrictions. If an authenticated victim visits the attacker's page and interacts with it, the attacker could trick the victim into performing unintended actions, resulting in a low impact on integrity. There is no impact on confidentiality and availability.
