CVE-2026-27379
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 NextScripts NextScripts social-networks-auto-poster-facebook-twitter-g allows Object Injection.This issue affects NextScripts: from n/a through <= 4.4.7.
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 confidenceA PHP Object Injection vulnerability exists in the NextScripts social-networks-auto-poster plugin due to unsafe deserialization (unserialize()) of untrusted data. This allows authenticated attackers to inject arbitrary PHP objects and potentially achieve remote code execution through gadget chains present in the application or loaded plugins.

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 the NextScripts plugin is installedCheck your WordPress plugins directory or WordPress admin panel for the 'NextScripts social-networks-auto-poster' plugin. Look for the plugin folder typically named 'nextscripts-snap' or similar in wp-content/plugins/Affected if The plugin is present in the WordPress installation
-
Identify the installed plugin versionAccess the plugin files and locate the main PHP file (often named snap.php, index.php, or similar in the plugin root). Open it and look for a version constant or header comment that declares the version number, for example: 'Version: x.x.x'Affected if Unable to determine the version or version is unknown
-
Locate unserialize() usage in plugin codeSearch all PHP files in the plugin directory for occurrences of 'unserialize('. Use grep or a text editor to find all instances. Review each call to see what data is being deserializedAffected if The plugin contains any unserialize() calls on data that could originate from user input, request parameters, or external sources
-
Check if unserialize processes external inputFor each unserialize() call found, trace the data source backward to determine if it comes from $_GET, $_POST, $_REQUEST, database fields, API responses, or other user-controllable sources. Look at function parameters and variable assignments leading to the unserialize callAffected if Any unserialize() call processes data that originates from request parameters, user profiles, or external sources without prior validation or sanitization
If the NextScripts social-networks-auto-poster plugin is installed and contains unserialize() calls that process data from user-controlled or external sources, the environment is affected by this PHP Object Injection vulnerability.

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 the NextScripts plugin to version 4.4.8 or later once available. If no patch exists, disable the plugin immediately and review server logs for exploitation attempts.
