CVE-2025-26349
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-23 "Relative Path Traversal" in the file upload mechanism in Q-Free MaxTime less than or equal to version 2.11.0 allows an authenticated remote attacker to overwrite arbitrary files 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 · moderate confidenceA relative path traversal (CWE-23) vulnerability exists in the file upload mechanism of Q-Free MaxTime version 2.11.0 and below. An authenticated remote attacker can craft HTTP requests containing path traversal sequences (e.g., '../') to escape the intended upload directory and write files to arbitrary locations on the server's filesystem.

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 installation versionLocate the version number through the product's admin interface, configuration files, or HTTP banner. Common paths include the web admin panel, an 'about' page, or a version/config file in the installation directory.Affected if The installed version is 2.11.0 or below.
-
Confirm file upload feature is accessibleDetermine whether the file upload functionality is enabled and accessible to authenticated users. This may be found in the web interface under upload forms, attachment features, or file management sections.Affected if File upload functionality is available to authenticated users.
-
Review upload endpoint configurationInspect the file upload handler or endpoint configuration. Look for how the target upload directory is specified in the application configuration or code.Affected if The upload path handling does not sanitize path traversal sequences ('../') or use basename() to strip directory components.
-
Test upload path behavior (if authorized)If you have a test environment, attempt a controlled upload with a path containing '../' sequences to verify whether the application properly restricts the final write location.Affected if The application allows escaping the intended upload directory via path traversal sequences.
A user is affected if MaxTime version 2.11.0 or below is installed AND the file upload feature is accessible to authenticated users without proper path traversal sanitization.

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 dataUpgrade to a version greater than 2.11.0 when available. In the interim, implement strict input validation on file upload paths using basename() to strip directory components, store uploads in a non-executable directory with restricted filesystem permissions, and validate file types/content.
