AI-suggested

Since this is a configuration-related issue involving the COEP header, it is recommended to configure the Cross-Origin-Embedder-Policy header properly to enforce cross-origin isolation. Monitor vendor advisories for any official remediation guidance or patches.

Description

HCL AION has a vulnerability due to a missing or insecure Cross-Origin-Embedder-Policy (COEP) header. This flaw weakens cross-origin isolation by allowing embedded cross-origin resources to load without explicit permission, which may lead to unintended behavior or exposure of sensitive information under certain conditions. The vulnerability is classified as CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor).
