HCL AION is affected by a Missing Security Response Headers vulnerability.

MEDIUM 5.3EPSS 0.18%

Does this matter?

Lower severity and a low EPSS score (0.18%). Track it; it rarely justifies an emergency change on its own.

Description

HCL AION is affected by a Missing Security Response Headers vulnerability. The absence of standard security headers may weaken the application’s overall security posture and increase its susceptibility to common web-based attacks.
