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 axiomthemes m2 | Construction and Tools Store m2-ce allows Object Injection.This issue affects m2 | Construction and Tools Store: from n/a through <= 1.1.2.
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 PHP Object Injection vulnerability exists in the axiomthemes m2 | Construction and Tools Store Magento theme due to unsafe deserialization of untrusted data. This critical flaw (CVSS 9.8) allows attackers to inject malicious PHP objects, potentially leading to remote code execution by leveraging magic methods like __wakeup or __destruct.

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 the axiomthemes m2 theme is installedCheck your Magento 2 installation for the presence of the axiomthemes m2 | Construction and Tools Store theme. Look in app/design/frontend/ or vendor/ directory for 'axiomthemes' or 'm2' theme folders.Affected if The theme folder named 'axiomthemes', 'm2', or 'Construction' is present in the frontend design directory.
-
Determine the installed theme versionCheck the theme's composer.json, theme.xml, or registration.php file typically found in app/design/frontend/axiomthemes/m2/ or vendor/axiomthemes/m2/ for the version number.Affected if The reported version is 1.1.2 or lower.
-
Identify unsafe deserialization calls in theme codeSearch all PHP files within the theme directory for the use of unserialize() function, particularly any that process user-supplied input, request parameters, or data from external sources.Affected if The theme contains unserialize() calls that handle untrusted input.
-
Verify the theme is active in MagentoRun the Magento CLI command: php bin/mongo theme:list or check the Magento admin panel under Content > Design > Themes to confirm the theme is configured as active.Affected if The axiomthemes m2 theme is set as the active design theme for the store.
-
Check for web input entry pointsReview any theme-related controllers, observers, or template files that accept data via GET/POST parameters, cookies, or HTTP headers and pass this data to unserialize().Affected if User-controllable input can reach unsafe unserialize() calls in the theme.
Your environment is affected if the axiomthemes m2 Construction and Tools Store theme (version 1.1.2 or lower) is installed and active, and contains unsafe unserialize() calls that process external input.

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 dataUpgrade to version 1.1.3 or later if available; otherwise, disable the affected theme component and implement input validation on all deserialized data streams.
