CVE-2026-6411

MAXHUB Pivot Client Application Use of a Broken or Risky Cryptographic Algorithm

Published May 7, 2026 CVSS 3.1 · 7.3 High EPSS < 1% KEV · Not listed
Description
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.

Remediation

Vendor Solution

MAXHUB recommends users upgrade the Pivot client application to v1.36.2 or newer. The remediation has been made available through an OTA update. Users running v1.36.2 or later are not affected and need only ensure they continue to maintain the latest version. At this time, MAXHUB is not aware of any public exploitation of this issue.
