CVSS 4.2 (medium) · published 2026-11-06
HCL AION is affected by a vulnerability where the Cross-Origin-Embedder-Policy (COEP) header was missing or insecure, so embedded cross-origin resources were not required to explicitly grant permission. This weakens cross-origin isolation, potentially resulting in unintended behavior or security impact under certain conditions.
