CVE-2025-60229
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 Themeton Lagom allows Object Injection. This issue affects Lagom: from n/a through 2.0.
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 confidenceDeserialization of Untrusted Data vulnerability in Themeton Lagom theme allows PHP Object Injection via insecure use of unserialize() on user-controlled input. This can lead to code execution or other malicious object manipulation depending on available POP chains.

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 Themeton Lagom theme is installedCheck the wp-content/themes/ directory for the 'lagom' or 'themeton-lagom' folder, or list installed WordPress themes via 'wp theme list' commandAffected if The Lagom theme by Themeton is present in the WordPress themes directory
-
Locate insecure unserialize() calls in theme PHP filesSearch theme PHP files for pattern: grep -r 'unserialize' /path/to/wp-content/themes/lagom/ or use IDE search across the theme directoryAffected if PHP files contain unserialize() function calls, particularly on data derived from external sources
-
Verify if unserialize() receives user-controlled inputExamine the context of found unserialize() calls - check if the input comes from $_POST, $_GET, $_COOKIE, $_REQUEST, or database values that can be influenced by usersAffected if The unserialize() call processes data that originates from HTTP request parameters, cookies, or other user-controllable sources without prior sanitization
-
Check if vulnerable code is in accessible code pathReview the functions/classes containing unserialize() to determine if they are called during normal page loads, AJAX requests, or admin actions - examine add_action/add_filter hooks in the themeAffected if The vulnerable unserialize() is reachable without authentication or is reachable through standard WordPress hooks that handle incoming requests
-
Identify potential POP chain gadgets in the theme or pluginsSearch for PHP classes with magic methods (__destruct, __wakeup, __toString, __invoke) in the theme and active plugins that could form a POP chain when combined with the unserialize() vulnerabilityAffected if Classes with dangerous magic methods exist in the theme or installed plugins that could be chained for code execution
A user is affected if the Themeton Lagom theme is installed AND contains unserialize() calls that process user-controlled input without prior validation, especially if exploitable POP chain gadgets are present in the theme or plugins.

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 insecure unserialize() calls with safe alternatives like json_decode(). If patching is not possible from the theme vendor, consider alternative theming solutions or implement input validation/filtering at the application layer.
