Technical details
The vulnerability stems from a missing or improperly configured Cross-Origin-Embedder-Policy (COEP) header in HCL AION, which weakens cross-origin isolation protections. This allows embedded cross-origin resources to execute without explicit permission grants, potentially leading to unintended behavior or security impact. The attack requires network access and specific cross-origin resource embedding conditions.
