No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

This vulnerability, in the MAXHUB Pivot client application versions prior to v1.36.2, may allow an attacker to obtain encrypted tenant email addresses and related metadata from any tenant. Due to the presence of a hardcoded AES key within the application, the encrypted data can be decrypted, enabling access to tenant email addresses and associated information in cleartext. Furthermore, an attacker may be able to cause a denial-of-service condition by enrolling multiple unauthorized devices into a tenant via MQTT, potentially disrupting tenant operations.
