CVE-2026-26341 is a vulnerability categorized under CWE-1392 (Use of Default Credentials) affecting Tattile s.r.l.'s Smart+, Vega, and Basic device families running firmware versions 1.181.5 and prior. The core issue is that these devices ship with default administrative credentials that are not enforced to be changed during installation or commissioning processes. This design flaw allows any attacker who can reach the device's management interface over the network to authenticate using the default username and password without requiring any prior authentication or user interaction. Once authenticated, the attacker gains administrative privileges, enabling them to modify device configurations, access sensitive data, and potentially pivot to other network resources. The vulnerability is network exploitable (AV:N), requires no privileges (PR:N), no user interaction (UI:N), and impacts confidentiality, integrity, and availability at a high level (VC:H, VI:H, VA:H). The scope is limited to the device itself (SC:N), and the vulnerability does not propagate beyond the device (SI:N, SA:N). Although no public exploits have been reported yet, the critical CVSS score of 9.3 reflects the severity and ease of exploitation. The lack of forced credential changes during setup is a significant security oversight, exposing these devices to unauthorized administrative access and potential compromise.

The impact of CVE-2026-26341 is severe for organizations deploying Tattile Smart+, Vega, and Basic devices. Unauthorized administrative access can lead to full compromise of device configurations and sensitive data, undermining confidentiality and integrity. Attackers could alter device settings, disable security controls, or extract sensitive information, potentially affecting downstream systems relying on these devices. In environments where these devices are part of critical infrastructure or surveillance systems, such compromise could disrupt operations or facilitate further network intrusion. The vulnerability’s ease of exploitation without authentication or user interaction increases the risk of automated or opportunistic attacks. Organizations may face operational downtime, data breaches, and compliance violations if exploited. The absence of forced credential changes during installation means many devices may remain vulnerable in the field, amplifying the potential attack surface globally.

To mitigate CVE-2026-26341, organizations should immediately audit all Tattile Smart+, Vega, and Basic devices to identify affected firmware versions. The primary mitigation is to change default credentials to strong, unique passwords immediately upon deployment or discovery. Since the firmware does not enforce this, manual intervention is critical. Network segmentation should be implemented to restrict access to device management interfaces only to trusted administrators and systems. Employ network-level access controls such as firewalls and VPNs to limit exposure. Monitoring and logging access to these devices can help detect unauthorized attempts. Where possible, update the firmware to versions beyond 1.181.5 if patches become available. If no patches exist, consider compensating controls such as disabling remote management interfaces or replacing vulnerable devices. Educate installation and operations teams to enforce credential changes as a mandatory step in device commissioning. Regular vulnerability assessments and penetration testing should include checks for default credentials on these devices.
