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

Local File Inclusion vulnerability in WP Shuffle Subscribe to Unlock Lite plugin allows attackers to include arbitrary PHP files from the server due to improper control of filename parameters in include/require statements, potentially leading to code execution.

MitigationUpdate to a patched version of the plugin. If no patch is available, disable the plugin and review code to add proper input validation/sanitization on file path parameters used in include/require functions.

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 the plugin is installed
    In WordPress admin dashboard, go to Plugins > Installed Plugins and look for 'WP Shuffle Subscribe to Unlock Lite' or check the plugin files in wp-content/plugins/ directory for the plugin folder
    Affected if The plugin is present in the WordPress installation
  2. Identify the installed plugin version
    Check the plugin's main PHP file (usually index.php or the main plugin file) for the 'Version' header comment in the file header, or look in the plugin's readme.txt file
    Affected if The installed version matches or falls within the vulnerable version range (compare against the official vulnerability advisory for specific version numbers)
  3. Confirm the plugin is active
    In WordPress admin > Plugins, check if 'WP Shuffle Subscribe to Unlock Lite' shows as 'Active'
    Affected if The plugin is active and accessible to potentially malicious users
  4. Check for exposure of vulnerable include/require code
    Review plugin PHP files for include/require statements that use unsanitized variables for file paths (look for patterns like 'include($_GET[...])' or 'require($variable)')
    Affected if The plugin contains include/require statements using user-controllable file paths without proper validation

If the plugin is installed and active, and its code contains include/require statements with unsanitized file path parameters, the environment is likely affected by this LFI vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

From vendor data
Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update to a patched version of the plugin. If no patch is available, disable the plugin and review code to add proper input validation/sanitization on file path parameters used in include/require functions.
