CVE-2025-67619
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 designthemes Kids Heaven kids-world allows Object Injection.This issue affects Kids Heaven: from n/a through <= 3.2.
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 confidenceThe Kids Heaven theme for WordPress contains a deserialization vulnerability (CWE-502) that allows unauthenticated attackers to inject PHP objects by passing crafted serialized data. This object injection can potentially lead to remote code execution if magic methods or POP chains exist in the theme or in any 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.
-
Confirm Kids Heaven theme installationNavigate to wp-content/themes/kids-heaven/ and locate style.css or functions.php to read the theme version comment header, or query the WordPress database for active theme detailsAffected if The theme is installed and active, and the version falls within any known affected range (or is unpatched for this deserialization flaw)
-
Locate unsafe unserialize() calls in theme codeSearch all PHP files in wp-content/themes/kids-heaven/ for the pattern 'unserialize(' using grep, grep -r "unserialize(" /path/to/wp-content/themes/kids-heaven/, or a file search toolAffected if Any unserialize() call exists in the theme files, indicating potential vulnerability to object injection
-
Identify input sources feeding unserialize()For each unserialize() call found, trace back the variable passed into it; examine the surrounding code to determine if the data originates from $_GET, $_POST, $_COOKIE, file imports, or API inputsAffected if The unserialize() call processes data from user-controlled sources without prior sanitization or validation
-
Check for magic methods in theme codeSearch the theme PHP files for magic method definitions: __destruct, __wakeup, __toString, __get, __set, __call using grep or code inspectionAffected if Magic methods exist in the theme and could be triggered via the deserialization gadget chain, potentially enabling RCE
A user is affected if the Kids Heaven theme is installed with active unserialize() calls that handle untrusted input, combined with exploitable magic methods or POP chains 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 unsafe unserialize() calls with json_decode() or implement proper whitelist validation before deserialization. Additionally, ensure no vulnerable POP chains exist by removing or securing any destructible magic methods in the theme code.
