Hubitat Elevation Hubs Vulnerability Enables Privilege Escalation (ICSA-26-022-06)
CISA warns of a privilege escalation flaw in Hubitat Elevation Hubs, allowing authenticated attackers to gain unauthorized device control. Patch immediately.
Hubitat Elevation Hubs Vulnerability Exposes Smart Home Systems to Privilege Escalation
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has disclosed a critical vulnerability in Hubitat Elevation Hubs that could enable authenticated attackers to escalate privileges and manipulate devices beyond their authorized scope. The flaw, tracked under advisory ICSA-26-022-06, was published on January 22, 2026, as part of CISA’s Industrial Control Systems (ICS) advisories.
Technical Details
While CISA’s advisory does not specify the exact CVE ID or technical root cause, the vulnerability allows an authenticated attacker to bypass access controls and gain elevated privileges. This could result in unauthorized control over connected smart home devices, including locks, sensors, and automation systems linked to the Hubitat platform.
Affected versions of Hubitat Elevation Hubs are listed in the CSAF (Common Security Advisory Framework) document, though specific version numbers were not detailed in the original advisory.
Impact Analysis
Successful exploitation of this flaw poses significant risks to smart home and IoT environments, including:
- Unauthorized device control: Attackers could manipulate smart locks, cameras, or environmental systems.
- Lateral movement: Compromised hubs may serve as an entry point for further network infiltration.
- Privacy violations: Unauthorized access to sensors or cameras could expose sensitive personal data.
Given the increasing adoption of smart home automation in both residential and commercial settings, this vulnerability underscores the need for robust access control mechanisms in IoT ecosystems.
Recommendations for Security Teams
CISA urges users and administrators to take the following actions:
- Apply patches immediately: Monitor Hubitat’s official channels for firmware updates addressing this vulnerability.
- Review access controls: Restrict hub access to authorized users and devices, leveraging network segmentation where possible.
- Monitor for suspicious activity: Audit logs for unusual device interactions or privilege escalation attempts.
- Follow CISA’s ICS advisories: Stay informed on emerging threats via CISA’s ICS Advisories page.
