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
The Simple File List plugin for WordPress is vulnerable to arbitrary file modification due to insufficient authorization checks in all versions up to, and including, 6.3.7. This makes it possible for unauthenticated attackers to delete and modify files on the serve. This vulnerability is exploitable even when the administrator has not enabled the AllowFrontManage setting, because the is_admin() check unconditionally short-circuits the guard before that setting is evaluated.

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

The Simple File List WordPress plugin (versions up to 6.3.7) has a broken access control vulnerability where the is_admin() check short-circuits before the AllowFrontManage setting is evaluated, allowing unauthenticated attackers to arbitrarily delete or modify files on the server regardless of the admin configuration.

MitigationUpdate the plugin to version 6.3.8 or later which properly evaluates authorization before the is_admin() check. If immediate patching is not feasible, disable or remove the plugin until the update can be applied.

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. Confirm Simple File List plugin is installed
    Navigate to WordPress admin > Plugins and verify Simple File List appears in the list of installed plugins, or inspect the plugin files in /wp-content/plugins/simple-file-list/ for the main PHP file containing the version header
    Affected if The plugin is not installed
  2. Identify the installed plugin version
    Locate the plugin version number in the plugin header of the main file (ee-simple-file-list.php or similar) within the plugin directory, or view the version displayed on the Plugins page in WordPress admin
    Affected if Version is 6.3.7 or earlier
  3. Check if AllowFrontManage setting is enabled
    In WordPress admin, go to Simple File List settings and look for the 'Allow Front-End Manage' or 'AllowFrontManage' option; alternatively, inspect the plugin options in the wp_options table where the setting is stored
    Affected if AllowFrontManage is set to enabled or yes (this configuration combined with vulnerable version creates the exposure)
  4. Verify file operation endpoints are accessible
    Test access to the plugin AJAX endpoints or file management URLs (typically under /wp-admin/admin-ajax.php?action=eeFileList... or similar) using an unauthenticated browser or curl request to confirm they respond without login
    Affected if Unauthenticated requests to file delete/modify endpoints return success rather than redirecting to login

If Simple File List plugin is installed at version 6.3.7 or earlier AND AllowFrontManage is enabled, the environment is affected by this unauthenticated file manipulation vulnerability.
