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 Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in CocoBasic Neresa neresa-wp allows PHP Local File Inclusion.This issue affects Neresa: from n/a through <= 1.3.

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

This is a PHP Local File Inclusion (LFI) vulnerability in the CocoBasic Neresa WordPress theme (version 1.3 and below). The vulnerability allows authenticated or unauthenticated attackers to include arbitrary PHP files from the server file system, potentially leading to sensitive file disclosure (like wp-config.php) or remote code execution if an attacker can control the included files.

MitigationUpdate the Neresa theme to the latest patched version. If no update is available, disable or remove the theme. Additionally, ensure PHP configuration sets allow_url_include=0 and allow_url_fopen=0, and audit the theme code for proper input validation on include/require statements.

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. Identify if Neresa theme is installed
    Check for the presence of the Neresa theme directory in your WordPress installation at /wp-content/themes/neresa/
    Affected if The neresa theme directory exists in the themes folder
  2. Determine the installed Neresa theme version
    Open the style.css file in /wp-content/themes/neresa/ and locate the 'Version:' header in the theme comments, or check theme.json if present for a version field
    Affected if The reported version is 1.3 or lower
  3. Check for vulnerable include/require code patterns
    Search the Neresa theme PHP files for include, require, include_once, or require_once statements that use user-supplied input (such as $_GET, $_POST, or $_REQUEST variables) without proper sanitization
    Affected if The theme contains include/require statements that directly incorporate unsanitized request parameters
  4. Verify PHP allow_url_include setting
    Check your php.ini file or run 'php -i' and look for the allow_url_include directive
    Affected if allow_url_include is set to On (1), which would allow URL-based file inclusion in addition to local file inclusion
  5. Test for unauthenticated access to vulnerable endpoints
    Review the theme's PHP files for any AJAX handlers or direct-access scripts that process include/require parameters without requiring authentication
    Affected if The theme exposes include/require functionality to unauthenticated users

You are affected if the Neresa theme version is 1.3 or lower AND the theme contains include/require code that processes unsanitized user input, especially if accessible to unauthenticated users.

Mitigation

Update the Neresa theme to the latest patched version. If no update is available, disable or remove the theme. Additionally, ensure PHP configuration sets allow_url_include=0 and allow_url_fopen=0, and audit the theme code for proper input validation on include/require statements.
