CVE-2026-75108 next-terminal CVE debrief

Who should care

Defenders responsible for authentication, asset management, and network security should assess exposure and prioritize remediation. This includes teams managing Next Terminal deployments, security teams monitoring for unusual activity, and asset owners verifying access controls. The vulnerability's medium severity and potential impact on asset information disclosure and unauthorized actions make it a priority for these stakeholders to review and address.

Why it matters

CVE-2026-75108 allows authenticated users to bypass authorization checks in Next Terminal, potentially leading to asset information disclosure and unauthorized actions.

• Authenticated users can probe unauthorized assets
• Wake-on-LAN packets can be triggered on unauthorized assets
• Asset information disclosure, including display names and network addresses
• Potential for lateral movement or escalation of privileges

Technical summary

CVE-2026-75108 is a medium-severity vulnerability in Next Terminal, allowing authenticated users to bypass per-asset authorization checks on portal ping and wake-on-LAN endpoints. This could lead to asset information disclosure and unauthorized actions.
