CVE-2025-26344
Published: 12 February 2025
Summary
CVE-2025-26344 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 Exploit Public-Facing Application (T1190); 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-3 (Access Enforcement).
Deeper analysis
CVE-2025-26344 is a missing authentication vulnerability (CWE-306) located in the maxprofile/guest-mode/routes.lua component of Q-Free MaxTime versions 2.11.0 and earlier. The flaw permits unauthenticated remote attackers to activate passwordless guest mode by sending specially crafted HTTP requests to the affected routes.
An attacker with network access can exploit the issue without credentials or user interaction, achieving full control over the guest-mode configuration. Successful exploitation yields high impact across confidentiality, integrity, and availability, consistent with the CVSS 9.8 base score.
The sole referenced advisory, published by Nozomi Networks, details the vulnerability and is the primary source of public technical information. EPSS scores remain low, with a current value of 0.0099 and a peak of 0.0162, indicating limited observed exploitation interest to date.

AC-14 directly restricts and documents permitted actions without identification or authentication, preventing unauthenticated attackers from enabling passwordless guest mode via crafted HTTP requests.
AC-3 enforces approved authorizations for access to system resources, ensuring critical functions like the guest-mode endpoint require authentication.
IA-9 mandates identification and authentication for system services as a prerequisite to access, blocking unauthenticated exploitation of the vulnerable routes.lua endpoint.
