CVE-2026-76977: SAP SE SAPUI5FRAME Options Allowlist

Medium severity, CVSS 4.3. EPSS: 0.4% chance of exploitation in the next 30 days.

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.
