CVE-2026-39523
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 Solene Core <= 2.3.2 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 Solene Core version 2.3.2 and earlier allows remote attackers to read arbitrary files on the server without any authentication credentials, potentially exposing sensitive configuration files, credentials, or source code.

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 Solene Core installation and versionLocate the Solene Core installation directory and check the version file or banner. Common locations include /opt/solene/, /var/www/solene/, or the application's main executable. Look for a version file, or run the application binary with a version flag if available.Affected if The installed version is 2.3.2 or earlier.
-
Verify web service is exposedCheck if Solene Core's web interface or API is listening on a network port. Use netstat or ss to list listening ports (e.g., ports 80, 443, 8080). Confirm the service is bound to an IP address accessible from the network.Affected if The web service is exposed to network access without firewall restrictions.
-
Confirm authentication is not enforcedAttempt to access the Solene Core web interface or API endpoints without providing credentials. Check if the HTTP response returns valid content or restricted resources without a login session or API key.Affected if Unauthenticated requests receive valid HTTP responses and can access application endpoints.
-
Identify vulnerable request parameterReview application logs or web server access logs for requests containing directory traversal patterns (e.g., ../../etc/passwd). If logs are unavailable, test the suspected LFI parameter by submitting requests with path traversal sequences to common input points.Affected if Requests with ../ sequences return file contents or trigger errors revealing file paths.
-
Check for input validation controlsExamine the application configuration files for any input validation, allowlisting, or web application firewall settings. Look for regex patterns, sanitization functions, or security middleware in the configuration directory.Affected if No input validation or allowlisting controls are configured, or traversal sequences are not filtered.
A user is affected if Solene Core version 2.3.2 or earlier is installed, the web service is network-accessible, and the directory traversal endpoint accepts unauthenticated requests without 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 Solene Core to a version beyond 2.3.2 and implement input validation/allowlist controls to prevent directory traversal attacks.
