CVE-2025-23944
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 bulktheme WOOEXIM wooexim allows Object Injection.This issue affects WOOEXIM: from n/a through <= 5.0.0.
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 confidenceThe WOOEXIM plugin for WordPress/WooCommerce contains a deserialization vulnerability where untrusted data is passed to PHP's unserialize() function, allowing an attacker to inject malicious PHP objects. This object injection can lead to remote code execution if suitable magic methods exist in the application or connected 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 WOOEXIM plugin is installedNavigate to WordPress admin dashboard > Plugins > Installed Plugins, or inspect the /wp-content/plugins/ directory for a folder named 'wooxim' or 'wooexim'Affected if The WOOEXIM plugin is present in the WordPress installation
-
Determine installed WOOEXIM versionIn WordPress admin, go to Plugins > Installed Plugins and locate WOOEXIM; the version number is displayed below the plugin name. Alternatively, check the main plugin file (typically /wp-content/plugins/wooxim/wooxim.php) for a 'Version' header in the file commentsAffected if The installed version matches or falls within the range of versions known to contain the deserialization vulnerability
-
Identify accessible unserialize() entry pointsReview plugin source code for calls to unserialize() function, particularly those processing data from user-supplied sources such as GET/POST parameters, cookies, or AJAX endpoints. Common patterns include: unserialize($_POST['data']), unserialize($_GET['payload']), or similar. Use grep: grep -r "unserialize" /wp-content/plugins/wooxim/Affected if The plugin contains unserialize() calls that process untrusted external input without prior sanitization
-
Check for publicly accessible AJAX or admin endpointsInspect the plugin's PHP files for registered action hooks (add_action) targeting wp_ajax_ or wp_ajax_nopriv_ prefixes, which expose functionality via /wp-admin/admin-ajax.php or front-end AJAX endpoints. Also check for admin-post.php handlersAffected if The vulnerable unserialize() code is reachable through an unauthenticated or low-privilege AJAX or admin endpoint
A user is affected if WOOEXIM is installed, the installed version contains the vulnerable unserialize() code, and that code processes untrusted input from an accessible endpoint.

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 WOOEXIM to the latest version if available, or disable the plugin until a patch is released. If the plugin is essential, review and sanitize all data passed to unserialize() calls.
