CVE-2025-23819
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 · uneditedImproper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in Marco Milesi WP Cloud cloud allows Absolute Path Traversal.This issue affects WP Cloud: from n/a through <= 1.4.3.
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 confidenceA path traversal vulnerability in WP Cloud plugin versions up to 1.4.3 allows attackers to perform absolute path traversal, potentially accessing files outside the intended web root directory. The vulnerability stems from insufficient validation of file path inputs, enabling malicious path references like /etc/passwd or other sensitive system files.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify WP Cloud plugin versionLocate the WP Cloud plugin directory in wp-content/plugins and read the main plugin file header for the Version field, or view it in WordPress admin under Plugins > Installed PluginsAffected if Version is 1.4.3 or lower
-
Confirm plugin is activeCheck WordPress admin Plugins page to verify WP Cloud plugin is currently activatedAffected if Plugin is active and version is 1.4.3 or lower
-
Identify file handling functionalityExamine plugin source files for functions that accept file path parameters, particularly code that performs file operations like include, require, file_get_contents, or fopen with user-controlled inputAffected if The plugin contains file handling code that processes path inputs from requests
-
Review path validation in file operationsInspect the identified file handling code for validation logic that prevents absolute path traversal (check for absence of checks blocking paths like /etc/passwd or similar system file references)Affected if No validation or sanitization exists to block absolute path traversal in file path inputs
The environment is affected if WP Cloud plugin version 1.4.3 or lower is installed and active, and the plugin processes file path inputs without proper validation to prevent absolute path traversal.

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 dataUpgrade WP Cloud to the latest version that addresses this path traversal vulnerability, and implement strict input validation on all file path parameters to prevent absolute path traversal attacks.
