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 Serhii Pasyuk Gmedia Photo Gallery grand-media allows PHP Local File Inclusion.This issue affects Gmedia Photo Gallery: from n/a through <= 1.23.0.
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 (LFI) vulnerability exists in the Gmedia Photo Gallery plugin (grand-media) where the application improperly handles filenames in include/require statements. Attackers can exploit this to include arbitrary local PHP files, potentially achieving remote code execution. The vulnerability affects all versions through 1.23.0.

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 if Gmedia Photo Gallery plugin is installedCheck your WordPress installation for the grand-media plugin folder in wp-content/plugins/ and confirm the plugin files existAffected if The grand-media plugin is present in the plugins directory
-
Check the installed plugin versionOpen the main plugin file (typically grand-media.php or index.php in the grand-media folder) and locate the version string in the plugin header commentAffected if The version is 1.23.0 or lower (the summary indicates all versions through 1.23.0 are affected)
-
Locate file inclusion code patternsSearch the plugin source code for include, require, include_once, or require_once statements that use variables in the path parameter without proper sanitizationAffected if File inclusion statements accept user-controlled input without validation or path traversal checks
-
Verify the vulnerable parameter is exposedTest whether the file inclusion parameter (the one used in include/require) can be manipulated through HTTP requests (e.g., GET/POST parameters)Affected if The parameter controlling the file inclusion is directly used in include/require statements and can be influenced by user input
You are affected if the grand-media plugin is installed with version 1.23.0 or lower and the file inclusion parameter accepts unsanitized user input.

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 dataFix requires source code changes to implement strict input validation on file inclusion parameters, restricting includes to whitelisted paths and preventing directory traversal sequences.
