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 RexCoin rexcoin allows PHP Local File Inclusion.This issue affects RexCoin: from n/a through <= 1.2.6.

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 ThemeREX RexCoin allows attackers to manipulate include/require statements by controlling the filename parameter, potentially executing arbitrary PHP code or reading sensitive files from the server.

MitigationImplement strict input validation on file inclusion parameters using allowlists, avoid user-supplied input in include/require statements, and ensure all file paths are sanitized and constrained to expected directories.

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 ThemeREX RexCoin theme is installed
    Check your WordPress installation themes directory for the RexCoin theme folder, typically found in wp-content/themes/ and confirm the theme name and version in style.css or theme.json
    Affected if ThemeREX RexCoin theme is present in the WordPress themes directory
  2. Locate PHP files that perform file inclusion
    Search the RexCoin theme directory for PHP files containing include, include_once, require, or require_once statements, particularly those using variables as the file path
    Affected if File inclusion functions are used within the theme PHP files
  3. Identify the vulnerable filename parameter
    Examine include/require statements to determine if a filename or path parameter can be influenced by user-supplied input such as GET, POST, or REQUEST superglobals
    Affected if User-controlled input from GET/POST/REQUEST parameters flows directly into include/require statements without validation
  4. Verify lack of input validation on file inclusion parameters
    Review the code around vulnerable include/require calls to check whether the filename parameter undergoes strict allowlist validation, path sanitization, or directory containment before use
    Affected if The filename parameter accepts arbitrary file paths without validation or sanitization against an allowlist of permitted files/directories
  5. Check file permissions and directory access
    Review whether the web server process has read access to sensitive system files or directories outside the expected theme/includes folders
    Affected if The PHP process can read files outside the intended theme directory through the LFI vulnerability

A user is affected if the ThemeREX RexCoin theme is installed and contains file inclusion code where user-supplied input is used in include/require statements without validation, allowing path manipulation.
