CVE-2025-23937
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 · uneditedImproper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in Alex Furr LinkedIn Lite linkedin-lite allows PHP Local File Inclusion.This issue affects LinkedIn Lite: from n/a through <= 1.0.
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 confidenceA PHP Local File Inclusion vulnerability exists in LinkedIn Lite <= 1.0 where user-supplied input is used in include/require statements without proper validation, allowing attackers to include and execute arbitrary local PHP files on the server.

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 LinkedIn Lite versionLocate the version file or header in the LinkedIn Lite installation (commonly in a version.php, composer.json, or metadata file at the project root)Affected if The installed version is 1.0 or lower
-
Search for dynamic include/require statementsSearch PHP source files for patterns like 'include($_', 'require($_', 'include_once($_', 'require_once($_' or similar constructs using user input ($_GET, $_POST, $_REQUEST) in file inclusion functionsAffected if Any include/require statements directly use unsanitized user-supplied input
-
Examine the file inclusion parameter handlingReview the code around the include/require statements found - check if the user-supplied parameter undergoes validation (allowlist, basename, path stripping) before being usedAffected if No input validation, sanitization, or allowlisting is performed on the file path before inclusion
-
Verify if arbitrary file paths can be suppliedIf the application exposes a parameter used in include/require (e.g., via URL query string), attempt to include a known local PHP file (like a configuration file) to confirm the vulnerability is exploitableAffected if The application allows path traversal or direct file path injection through user-accessible parameters
You are affected if LinkedIn Lite version 1.0 or lower is installed AND the codebase contains include/require statements using unsanitized user input without validation or allowlisting.

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 strict input validation using an allowlist approach for file inclusion, or refactor code to avoid dynamic file inclusion entirely.
