CVE-2025-68526
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 · uneditedDeserialization of Untrusted Data vulnerability in A WP Life Modal Popup Box modal-popup-box allows Object Injection.This issue affects Modal Popup Box: from n/a through <= 1.6.1.
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 confidenceThe Modal Popup Box WordPress plugin (versions <= 1.6.1) contains a deserialization of untrusted data vulnerability allowing Object Injection. The plugin uses PHP's unsafe unserialize() function on user-controlled input, enabling attackers to instantiate arbitrary objects and potentially trigger gadget chains for remote code execution, depending on available classes in the WordPress environment.

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.
-
Verify Modal Popup Box plugin is installedAccess WordPress admin panel under Plugins > Installed Plugins and look for 'Modal Popup Box' or inspect the wp-content/plugins directory for the modal-popup-box folderAffected if The plugin appears in the installed plugins list
-
Check installed plugin versionView the plugin version in the Plugins list in WordPress admin, or open wp-content/plugins/modal-popup-box/readme.txt and look at the 'Stable tag' entry, or check the plugin header in its main PHP fileAffected if The version listed is 1.6.1 or lower
-
Inspect plugin source code for vulnerable unserialize callsSearch plugin files for 'unserialize' by examining PHP files in wp-content/plugins/modal-popup-box/, looking for code patterns like unserialize($_GET[...]), unserialize($_POST[...]), or unserialize($_REQUEST[...])Affected if Any file contains an unserialize() call that processes input from $_GET, $_POST, or $_REQUEST superglobals without prior sanitization
-
Identify if plugin processes external request dataReview the plugin's PHP files to determine if it handles data from URL parameters or form submissions that could reach the unserialize callAffected if The plugin accepts and processes user-supplied data from HTTP requests that could be passed to the vulnerable unserialize function
A user is affected if the Modal Popup Box plugin version is 1.6.1 or lower AND the plugin code contains an unserialize() call that processes untrusted user input from HTTP request parameters.

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 to a patched version of the plugin that replaces unsafe unserialize() calls with secure deserialization methods like json_decode(), or implement proper input validation and sanitization before any deserialization occurs.
