CVE-2026-22471
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 maximsecudeal Secudeal Payments for Ecommerce secudeal-payments-for-ecommerce allows Object Injection.This issue affects Secudeal Payments for Ecommerce: from n/a through <= 1.1.
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 confidenceThis is a PHP Object Injection vulnerability caused by unsafe deserialization (unserialize()) of untrusted user input in the Secudeal Payments for Ecommerce plugin. Attackers can craft malicious serialized PHP objects to achieve remote code execution, depending on available gadget chains in the application or installed 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 Secudeal Payments plugin is installedLocate the Secudeal Payments for Ecommerce plugin in your application's plugin or module directory. Check the plugin header in the main PHP file for the version identifier, or look for a version file or readme.Affected if The Secudeal Payments for Ecommerce plugin is present in your environment and has a known version
-
Find unsafe unserialize() calls in plugin codeSearch the plugin source code files for the pattern 'unserialize(' using grep, a code search tool, or manual inspection. Focus on PHP files that handle form submissions, payment callbacks, API endpoints, or AJAX requests.Affected if The plugin contains unserialize() function calls
-
Verify user input reaches unserialize()Trace the data flow from user-controlled sources ($_POST, $_GET, $_COOKIE, $_REQUEST, or HTTP headers) to the identified unserialize() calls. Check if raw or base64-decoded data from these sources is passed directly to unserialize().Affected if User-supplied input from HTTP requests is passed to unserialize() without sanitization
-
Determine if gadget chains existExamine what classes and libraries are autoloaded or available in the application context. Check for common PHP gadget chain libraries or custom classes that could be exploited if object injection occurs.Affected if Vulnerable gadget chains or classes are available in the application that could be triggered via injected objects
You are affected if the Secudeal Payments plugin is installed, processes user input through unsafe unserialize(), and has exploitable gadget chains available in the application context.

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 dataReplace unsafe unserialize() calls with safer alternatives like json_decode() for data transport, or implement strict allowlist validation if deserialization is absolutely required. Review and sanitize all user-supplied data before processing.
