## Summary

HCL AION is affected by a missing or insecure HTTP Strict-Transport-Security header, which can let an attacker downgrade or intercept connections to the software. The attacker can reach it remotely over the network, but it requires low-privilege login and user interaction, and the bug needs specific conditions to have a security impact.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- HCL Software AION: V 2.6.0

## Description

HCL AION is affected by a vulnerability where the HTTP Strict-Transport-Security (HSTS) header was missing or insecurely configured, so browsers were not instructed to always use HTTPS. This may allow connections to be downgraded or intercepted, potentially resulting in unintended behavior or security impact under certain conditions.
