Clickjacking via insufficient parent-origin allowlist validation
Published Sep 8, 2026 · Updated Sep 8, 2026
Clickjacking in SAPUI5 Frame Options Allowlist allows remote attackers to induce unintended authenticated actions through a malicious page. The frame-options allowlist logic insufficiently validates the parent frame's origin, allowing a malicious origin to bypass its interaction-blocking layer. Exploitation requires an authenticated victim to visit the attacker-controlled page and interact with the framed application; the reported consequence is limited to unintended actions.
