Vulnerability from fkie_nvd - Published: 2026-09-08 01:17 - Updated: 2026-09-08 01:17
Severity
4.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N
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.
