Summary

CVE-2026-2414 is a critical-severity Authorization Bypass Through User-Controlled Key (CWE-639) vulnerability in Hypr Hypr. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 17.4th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 AC-3 (Access Enforcement) and SI-10 (Information Input Validation).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploitation for Privilege Escalation (T1068) and 1 other technique. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

AC-3 Access Enforcement good match

prevent

Enforces approved authorizations for access to system resources, directly preventing authorization bypass via user-controlled keys that enable privilege escalation.

SI-10 Information Input Validation good match

prevent

Validates the correctness of user-controlled inputs like keys, blocking manipulation that leads to authorization bypass and privilege escalation.

AC-6 Least Privilege partial match

prevent

Limits user and process privileges to the minimum necessary, reducing the potential impact and scope of privilege escalation even if a bypass occurs.

MITRE ATT&CK Enterprise TechniquesAI

T1068 Exploitation for Privilege Escalation Privilege Escalation

Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

Why these techniques?

Authorization bypass on public-facing HYPR Server directly enables remote unauthenticated exploitation (T1190) leading to privilege escalation (T1068).

NVD Description

Authorization bypass through User-Controlled key vulnerability in HYPR Server allows Privilege Escalation.This issue affects Server: from 9.5.2 before 10.7.2.

Deeper analysisAI

CVE-2026-2414 is an authorization bypass vulnerability caused by a user-controlled key in the HYPR Server, enabling privilege escalation. The issue affects HYPR Server versions from 9.5.2 up to but not including 10.7.2.

With a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), the vulnerability is exploitable remotely over the network by unauthenticated attackers with low complexity and no user interaction required. Successful exploitation allows attackers to achieve high-impact disruption to confidentiality, integrity, and availability through privilege escalation.

Mitigation details are available in the vendor's security advisory at https://www.hypr.com/trust-center/security-advisories. The vulnerability is addressed in HYPR Server version 10.7.2 and later.
