## Technical details

The vulnerability is a missing or misconfigured Cross-Origin-Resource-Policy (CORP) header in HCL AION, enabling cross-origin data leakage attacks. An attacker can craft a malicious website that fetches protected resources from a victim's AION instance. The attack requires the victim to visit an attacker-controlled page while authenticated to AION, but exploits a server-side configuration weakness rather than a code flaw.
