CVE-2025-57889
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 RealMag777 InPost Gallery inpost-gallery allows PHP Local File Inclusion.This issue affects InPost Gallery: from n/a through <= 2.1.4.5.
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 confidenceThis is a Local File Inclusion (LFI) vulnerability in the RealMag777 InPost Gallery plugin for WordPress. The plugin fails to properly validate user-supplied input used in PHP include/require statements, allowing attackers to read sensitive local files or potentially execute arbitrary PHP code through directory traversal attacks.

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.
-
Locate the plugin filesCheck the WordPress plugins directory (wp-content/plugins) for a folder related to InPost Gallery or RealMag777Affected if The plugin folder is not present, meaning the plugin is not installed
-
Identify the plugin versionOpen the main plugin PHP file and look for the version comment in the plugin header (e.g., 'Version: x.x.x')Affected if The version number cannot be determined or the plugin header is missing
-
Compare version to known vulnerable rangeObtain the affected version range from the CVE advisory and compare it against the installed version using the WordPress plugin repository or the plugin vendor changelogAffected if The installed version falls within the vulnerable range documented for this CVE
-
Inspect for user input in include/require statementsReview the plugin PHP source code, specifically looking for include(), require(), include_once(), or require_once() statements that incorporate request parameters (e.g., $_GET, $_POST) without sanitizationAffected if The plugin uses unsanitized user-supplied input in file inclusion functions, enabling directory traversal
-
Check if the vulnerable parameter is accessibleIdentify which GET/POST parameter is used in the insecure file inclusion and determine if it is accessible to unauthenticated users by examining the code flowAffected if The vulnerable parameter can be reached without authentication or specific privileges
The environment is affected if the RealMag777 InPost Gallery plugin is installed with a version within the vulnerable range and the code contains insecure file inclusion using user input that is externally accessible.

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 a whitelist approach, sanitize path inputs by removing directory traversal sequences (../), and avoid using user input directly in include/require statements. If file inclusion is necessary, use a predefined whitelist of allowed files.
