## Technical details

HCL AION is vulnerable to an information disclosure flaw (CWE-201) where specific operations trigger out-of-band (OOB) interactions. The vulnerability is characterized by the insertion of sensitive information into data sent to external systems. Exploitation requires an attacker to be on an adjacent network, have low-level privileges, and involves high complexity with a requirement for user interaction. If successfully exploited, this could lead to a loss of confidentiality, integrity, and availability, though the impact is limited.
