What Happened
A security flaw was found in Rently Smart Home systems that could let an attacker access sensitive user pins, including the master pin. This would allow the attacker to override normal user permissions and gain unauthorized access. The company that makes Rently Smart Home has already released a patch for this issue in late June, so users do not need to take any action. Organizations using these systems should ensure they are running the patched version.
Key Takeaways
- Rently Smart Home versions 20.1.0 and prior are vulnerable to insufficiently protected credentials (CVE-2026-75960).
- Successful exploitation allows an attacker to retrieve pins, including the Master Pin, overriding standard user permissions.
- The vendor patched the vulnerability in late June and no user action is required.
Affected Systems
- Rently Smart Home <=20.1.0

Detection Engineering Assessment
copy:
| Dimension | Rating | Rationale |
|---|---|---|
| EDR Visibility | Low | The vulnerability is in a smart home application, which may not be monitored by standard EDR solutions. |
| Network Visibility | Medium | Network traffic to and from the Rently Smart Home application could be monitored for anomalous access patterns. |
| Detection Difficulty | Moderate | Detecting exploitation requires visibility into application-specific credential access and privilege escalation events. |
Required Log Sources
- Application logs
- Network firewall logs
Hunting Hypotheses
copy:
| Hypothesis | Telemetry | ATT&CK Stage | FP Risk |
|---|---|---|---|
| An attacker may attempt to access or extract credential pins from the Rently Smart Home application. | Application logs for credential access or API calls requesting pin data. | Credential Access | Low, as legitimate pin access is typically restricted to authorized users. |
| An attacker may use the Master Pin to access restricted functionality or devices. | Application logs for authentication events using the Master Pin. | Privilege Escalation | Low, if Master Pin usage is rare and logged. |
Control Gaps
- Standard network firewalls may not inspect application-layer credential access.
- Lack of application-level logging for credential access events.
Key Behavioral Indicators
- Unauthorized access to Master Pin
- Anomalous API calls requesting pin data
False Positive Assessment

Recommendations
Immediate Mitigation
defender takeaway
- Verify against your organization's incident response runbook and team escalation paths before acting.
- Ensure Rently Smart Home systems are updated to the patched version released in late June.
Infrastructure Hardening
- Minimize network exposure for control system devices, ensuring they are not accessible from the internet.
- Locate control system networks and remote devices behind firewalls and isolate them from business networks.
- Use secure remote access methods such as VPNs, ensuring they are updated to the most current version.
User Protection
- Apply the vendor patch to all affected Rently Smart Home installations.
Security Awareness
- Follow established internal procedures for reporting suspected malicious activity to CISA.
