CVE-2025-0421Network attack vector

User interface overlay via unrestricted iframe rendering

Published Nov 19, 2025 · Updated Nov 19, 2025

Improper frame restriction in Shopside through 05022025 allows attackers to overlay its interface within a malicious iFrame. The application permits its interface to render inside an attacker-controlled iFrame instead of restricting cross-origin framing, but the affected page or control is undisclosed. Exploitation requires high-privileged access according to the published assessment; available advisories do not identify which actions or data the overlaid interface exposes.
