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 Mikado-Themes Stål stal allows Object Injection.This issue affects Stål: from n/a through < 1.7.
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 · moderate confidenceThe Stål theme by Mikado-Themes contains a deserialization vulnerability (CWE-502) that allows remote attackers to inject malicious PHP objects via untrusted serialized data. This object injection can potentially lead to code execution, file inclusion, or other attacks depending on available gadget chains in the application 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.
-
Confirm Stål theme installationCheck your WordPress/theme installation for the presence of the Stål theme by Mikado-Themes. This may be in your themes directory or bundled within a WordPress installation.Affected if The Stål theme by Mikado-Themes is installed on the system.
-
Identify Stål theme versionLocate the theme's version file, style.css header, or version constant within the Stål theme files. Compare the installed version to version 1.7 (the patched version).Affected if The installed version is lower than 1.7, or the version cannot be determined.
-
Locate deserialization entry pointsSearch the Stål theme source code for usage of unserialize(), eval(), include, or require statements that process user-controlled input. Focus on PHP files that accept data from HTTP requests.Affected if The theme contains code that deserializes untrusted input without validation.
-
Identify exposed input handlersReview your web server logs and application endpoints for requests that submit serialized PHP data (often identifiable by patterns like O: or a: in request bodies). Check PHP files for parameters passed to unserialize().Affected if Endpoints exist that accept serialized data from unauthenticated or authenticated users.
Your environment is affected if the Stål theme is installed with a version lower than 1.7 and contains accessible code paths that process untrusted serialized data.

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.
dbcve · scopedUpgrade the Stål theme to version 1.7 or later to obtain the patched version. If upgrading is not immediately feasible, disable the theme or restrict access to any endpoints that handle serialized input.
Stål theme version 1.7 or later
- 1. Check the current version of the Stål theme installed on your WordPress site
- 2. Navigate to Themes section in WordPress admin dashboard
- 3. If current version is below 1.7, update to version 1.7 or the latest available version
- 4. Verify the theme update was successful
- 5. Test critical site functionality after update to ensure compatibility
