Until an official fix is available, consider implementing appropriate security headers including a strict Cross-Origin-Opener-Policy to prevent cross-origin sharing of browsing contexts. Monitor vendor communications for updates on patches or official mitigations.
Description
HCL AION has a vulnerability due to a missing or insecure Cross-Origin-Opener-Policy (COOP) header.

Such attacks could lead to unintended behavior or security impacts under certain conditions. The vulnerability is classified as CWE-200, indicating exposure of sensitive information to unauthorized actors. The CVSS v3.1 base score is 4.8, reflecting a medium severity level. No affected versions or patch information are provided. There are no known exploits in the wild at this time.
