Summary

CVE-2025-26342 is a critical-severity Missing Authentication for Critical Function (CWE-306) vulnerability in Q-Free Maxtime. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 22.7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 AC-14 (Permitted Actions Without Identification or Authentication) and AC-2 (Account Management).

Deeper analysis

CVE-2025-26342 is a missing authentication vulnerability (CWE-306) affecting the file maxprofile/accounts/routes.lua in Q-Free MaxTime versions up to and including 2.11.0. The flaw resides in a critical function that handles user account creation and permits unauthenticated access over the network, resulting in a CVSS 3.1 base score of 9.8.

An unauthenticated remote attacker can send crafted HTTP requests to the affected endpoint and create arbitrary user accounts, including those with administrator privileges. Successful exploitation grants the attacker full administrative control over the MaxTime instance without requiring any prior credentials or user interaction.

A detailed advisory published by Nozomi Networks at the referenced URL describes the issue and is the primary source of public information on the vulnerability. The EPSS score remains low, with a recorded peak of 0.0162 and a current value of 0.0099, indicating limited observed exploitation interest to date.

MITRE ATT&CK Enterprise TechniquesAI

T1068 Exploitation for Privilege Escalation Privilege Escalation
Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.
T1136.001 Local Account Persistence
Adversaries may create a local account to maintain access to victim systems.
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?

Missing authentication in web application allows unauthenticated remote creation of arbitrary local administrator accounts, enabling T1190 (Exploit Public-Facing Application), T1068 (Exploitation for Privilege Escalation), and T1136.001 (Create Account: Local Account).

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

prevent

AC-14 directly mandates identification and restriction of critical functions like user creation that are permitted without authentication, preventing unauthenticated arbitrary account creation.

prevent

AC-3 enforces access control policies to block unauthenticated remote attackers from accessing the vulnerable user creation endpoint in maxprofile/accounts/routes.lua.

prevent

AC-2 governs account management processes to ensure only authorized entities can create users, including administrators, mitigating exploitation of the missing authentication.
