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 · unedited
Improper Control of Generation of Code ('Code Injection') vulnerability in jetmonsters Hotel Booking Lite motopress-hotel-booking-lite allows Remote Code Inclusion.This issue affects Hotel Booking Lite: from n/a through <= 5.2.3.

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 confidence

A code injection vulnerability in the motopress-hotel-booking-lite WordPress plugin allows remote attackers to inject and execute arbitrary code through improper control of code generation. The vulnerability stems from insufficient input validation on parameters used in dynamic code inclusion, enabling Remote Code Execution (RCE) without authentication.

MitigationUpgrade to a patched version of Hotel Booking Lite (version > 5.2.3) immediately. If no patch is available, disable the plugin or restrict access to the affected endpoints via web server configuration until a fix is released.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Hotel Booking Lite plugin is installed
    In WordPress admin, navigate to Plugins > Installed Plugins and look for 'Hotel Booking Lite' or 'motopress-hotel-booking-lite'. Alternatively, check the wp-content/plugins directory for a folder containing 'hotel-booking' or 'motopress'.
    Affected if The plugin is present in the WordPress installation
  2. Identify the installed plugin version
    In WordPress admin > Plugins, click 'View Details' on Hotel Booking Lite to see the version number. Alternatively, read the main plugin PHP file (usually plugin-root.php) and look for the 'Version' header in the plugin comment block.
    Affected if The version is 5.2.3 or lower
  3. Search for dynamic code inclusion patterns in plugin files
    Use grep or a file search to scan PHP files in the hotel-booking plugin directory for patterns like 'include($', 'require($', 'include_once($', 'require_once(' with variable parameters, especially where user input (GET/POST/REQUEST) parameters are passed directly to include/require statements.
    Affected if Dynamic includes using unsanitized input variables are found in the plugin code
  4. Verify if the vulnerable endpoint is accessible
    Test access to common dynamic inclusion endpoints by attempting requests with manipulated parameters. Check for PHP files that process $_GET, $_POST, or $_REQUEST parameters and use them in file inclusion operations without validation.
    Affected if Endpoints accepting dynamic file parameters without validation are accessible and respond to requests
  5. Check for recent unauthorized code execution indicators
    Review web server access logs (Apache/nginx) for suspicious POST/GET requests to hotel-booking plugin files with unusual parameter values, especially attempts to include remote files or unexpected PHP file paths. Also check for new/modified PHP files in the plugin directory.
    Affected if Log analysis reveals requests attempting code injection or unexpected file inclusions targeting the plugin

A user is affected if Hotel Booking Lite plugin version 5.2.3 or lower is installed AND the plugin contains vulnerable dynamic code inclusion patterns accessible without authentication.
