CVE-2025-39356
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 Chimpstudio Foodbakery Sticky Cart foodbakery-sticky-cart allows Object Injection.This issue affects Foodbakery Sticky Cart: from n/a through <= 3.2.
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 deserialization vulnerability in the Foodbakery Sticky Cart WordPress plugin (versions <= 3.2) allows unauthenticated attackers to inject arbitrary PHP objects by supplying crafted serialized data. This PHP Object Injection can potentially lead to remote code execution if suitable gadget chains exist within the application or loaded libraries.

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 Foodbakery Sticky Cart plugin is installedIn WordPress admin, go to Plugins > Installed Plugins and search for 'Foodbakery Sticky Cart' or check the /wp-content/plugins/ directory for the sticky-cart folderAffected if The plugin is present and active in the WordPress installation
-
Identify the installed plugin versionIn WordPress admin > Plugins > Installed Plugins, click on the plugin to view details and note the version number. Alternatively, check the main plugin file (e.g., sticky-cart.php) for the 'Version' header in the plugin comment blockAffected if The version is lower than any patched version released for this vulnerability (compare against publicly disclosed affected versions if available)
-
Check if deserialization input handling is accessibleReview the plugin source code for unserialize() calls on user-controlled data. Common entry points include AJAX actions, REST API endpoints, or form submissions. Search for patterns like 'unserialize($_POST[', 'unserialize($_GET[', or 'unserialize($_REQUEST' in the plugin filesAffected if The plugin contains unserialize() calls that process input from unauthenticated or low-privilege user sources without validation
-
Look for signs of exploitation attemptsReview WordPress debug logs (/wp-content/debug.log if enabled), server access logs, and the wp_options table for suspicious serialized data in plugin-related option names. Use grep or similar tools to search for known gadget chain class names in uploaded files or the databaseAffected if Unexplained serialized data appears in database fields or logs, or known PHP object injection gadget classes are present in the environment
You are affected if the Foodbakery Sticky Cart plugin is installed and its version contains the vulnerable deserialization flaw, particularly if the plugin accepts unserialize() input from user requests without proper validation.

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 dataUpdate to the latest patched version of Foodbakery Sticky Cart when available. Until patched, disable the plugin or deploy WAF rules to block serialized data in HTTP request parameters.
