CVE-2025-26342
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA CWE-306 "Missing Authentication for Critical Function" in maxprofile/accounts/routes.lua in Q-Free MaxTime less than or equal to version 2.11.0 allows an unauthenticated remote attacker to create arbitrary users, including administrators, via crafted HTTP requests.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThis is a critical authentication bypass vulnerability in Q-Free MaxTime where the user account creation endpoint (maxprofile/accounts/routes.lua) lacks any authentication check. An unauthenticated remote attacker can craft HTTP requests to create arbitrary users, including full administrator accounts, directly compromising the entire system.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify MaxTime versionLocate the installed MaxTime version number, typically found in the application itself, a version file, or the software release documentationAffected if The installed version is 2.11.0 or lower
-
Confirm endpoint existsLocate or access the file maxprofile/accounts/routes.lua in the MaxTime installation directory and verify it contains user creation handlersAffected if The routes.lua file exists and includes account creation logic
-
Test endpoint authenticationSend a crafted HTTP POST request to the user creation endpoint (typically /maxprofile/accounts/ or similar path in routes.lua) without providing any authentication credentialsAffected if The request succeeds and returns a user creation response without requiring authentication
-
Check for unauthorized admin accountsQuery the MaxTime user database or user management interface for newly created accounts with administrative privileges that were not created by legitimate administratorsAffected if Unexpected administrative user accounts exist in the system
-
Review access logsExamine HTTP server or application logs for POST requests to the accounts creation endpoint originating from unexpected IP addresses without prior authentication sessionsAffected if Unauthenticated requests to user creation endpoints appear in logs
You are affected if MaxTime version is 2.11.0 or lower AND the maxprofile/accounts/routes.lua user creation endpoint is accessible without authentication, allowing arbitrary administrative account creation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement authentication and authorization checks on the account creation endpoint in routes.lua to ensure only authenticated and authorized users can create new accounts. Consider updating to version >2.11.0 if a patched release is available.
