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 ThimPress BuilderPress builderpress allows PHP Local File Inclusion.This issue affects BuilderPress: from n/a through <= 2.0.1.

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 confidence

This is a PHP Local File Inclusion (LFI) vulnerability in the BuilderPress plugin by ThimPress. The vulnerability stems from improper control of filenames in include/require statements, allowing attackers to include arbitrary local files. This can lead to exposure of sensitive configuration files, source code, or in some scenarios, remote code execution.

MitigationUpdate BuilderPress to the latest patched version. If no patch is available, disable the plugin until a fix is released. Implement strict input validation on any user-controlled parameters used in file inclusion paths.

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. Verify BuilderPress plugin is installed
    List installed WordPress plugins via admin dashboard or run: wp plugin list --name=builderpress
    Affected if The BuilderPress plugin by ThimPress is present in the WordPress installation
  2. Determine installed BuilderPress version
    Check the plugin version in the plugin header file (usually builderpress/includes/index.php or via WordPress admin > Plugins > BuilderPress), or query it programmatically
    Affected if The installed version is older than the patched version or falls within an unpatched version range
  3. Identify file inclusion functions in plugin code
    Search the builderpress plugin directory for dynamic file inclusion patterns like include($..., require($..., include_once($..., or require_once($... where user input could control the path
    Affected if Unsandboxed file inclusion functions that accept variable input are found in the plugin code
  4. Inspect web server access logs for LFI patterns
    Review Apache, Nginx, or other web server access logs for requests to BuilderPress endpoints containing path traversal sequences such as ../, ..\, or direct file paths like /etc/passwd
    Affected if Suspicious requests with path traversal patterns targeting BuilderPress are present in the logs

The environment is affected if BuilderPress plugin is installed AND uses a version lacking the CVE patch AND the vulnerable file inclusion functionality is accessible to attackers.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update BuilderPress to the latest patched version. If no patch is available, disable the plugin until a fix is released. Implement strict input validation on any user-controlled parameters used in file inclusion paths.
