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 ThemeREX Dr.Patterson dr-patterson allows PHP Local File Inclusion.This issue affects Dr.Patterson: from n/a through <= 1.3.2.

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 PHP Local File Inclusion (LFI) vulnerability in the ThemeREX Dr.Patterson WordPress theme (versions through 1.3.2) allows attackers to include arbitrary local PHP files due to improper control of filename parameters in include/require statements. This can lead to remote code execution if attackers can upload malicious PHP files or access sensitive system files.

MitigationUpgrade to the latest version of the Dr.Patterson theme when a patch is released. As immediate mitigation, disable PHP execution in upload directories and implement strict whitelist-based input validation on all file inclusion parameters.

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 Dr.Patterson theme is installed
    Navigate to WordPress admin dashboard under Appearance > Themes, or inspect the /wp-content/themes/ directory for a folder named 'dr-patterson' or similar ThemeREX theme folder
    Affected if The Dr.Patterson theme by ThemeREX is present in the WordPress installation
  2. Determine installed theme version
    Check the theme's style.css file located in the theme folder for the 'Version:' header, or view the theme details in WordPress admin under Appearance > Themes
    Affected if The version is 1.3.2 or any earlier version through 1.3.2
  3. Identify vulnerable file inclusion code
    Search theme PHP files for include/require statements using parameter inputs, such as grep searches for patterns like 'include($_GET' or 'require($_REQUEST' within the theme folder
    Affected if The theme contains file inclusion statements that use unvalidated user-supplied parameters without sanitization
  4. Test for LFI parameter accessibility
    Attempt a benign include test by requesting a known file path through suspected parameters (e.g., ?file=../../../../wp-config.php) - only perform on non-production test systems
    Affected if The application includes or attempts to include files based on user-supplied input without proper validation, indicating the LFI vulnerability is present and exploitable
  5. Check PHP execution in upload directories
    Review .htaccess or server configuration files in /wp-content/uploads/ directories for PHP execution permissions, or check if no restrictions exist
    Affected if PHP execution is allowed in upload directories, which would allow uploaded malicious PHP files to be executed, escalating LFI to RCE

A user is affected if the ThemeREX Dr.Patterson theme version 1.3.2 or earlier is installed and the vulnerable file inclusion parameters are accessible without proper input validation.
