CVE-2026-39549
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 · uneditedUnauthenticated Local File Inclusion in Aperitif <= 1.5 versions.
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 confidenceUnauthenticated Local File Inclusion vulnerability in Aperitif versions 1.5 and below allows remote attackers to read arbitrary files on the server by manipulating file path parameters without requiring authentication.

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.
-
Confirm Aperitif is installedIdentify if the Aperitif application is running on the system. Check for Aperitif-related processes, web directories, or services. Look for the application in common web server directories or check installed packages.Affected if Aperitif software is present on the system
-
Check installed Aperitif versionLocate and read the version information for Aperitif. This may be in a version file, about page, headers, or configuration file. Common locations include a version.txt, composer.json, or the admin interface.Affected if The installed version is 1.5 or any version below 1.5
-
Verify web interface is accessibleDetermine if the Aperitif web interface is exposed and reachable. Check if HTTP/HTTPS ports for Aperitif are listening and accessible from the network.Affected if The web interface is accessible without authentication
-
Identify file path parameter endpointsReview the application for parameters that accept file paths or filenames. Look for URL patterns, form inputs, or API parameters that might accept file references. Common patterns include 'file=', 'path=', 'template=', or 'page=' parameters.Affected if The application accepts file path parameters that can be manipulated
-
Check for directory traversal protectionInspect the application's input handling for file path parameters. Test if the application properly validates and sanitizes path inputs, or allows directory traversal sequences like '../' in user-supplied file paths.Affected if Directory traversal sequences are not blocked or sanitized in file path parameters
The environment is affected if Aperitif version 1.5 or below is installed and has an accessible web interface with file path parameter handling that lacks proper input validation.

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 newer than 1.5, or implement strict input validation and whitelist-based file access controls to prevent directory traversal sequences in user-supplied file paths.
