CVE-2025-31924
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 Crafts & Arts crafts-and-arts allows Object Injection.This issue affects Crafts & Arts: from n/a through <= 2.5.
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 in the designthemes Crafts & Arts WordPress theme. The vulnerability stems from the theme deserializing untrusted user input (likely via PHP's unsafe unserialize() function), allowing attackers to inject arbitrary PHP objects. When combined with available 'gadget chains' in the application or surrounding WordPress environment, this can lead to remote code execution.

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.
-
Identify if Designthemes Crafts & Arts theme is installedLocate the theme directory in wp-content/themes/ and check for a folder named 'designthemes-crafts-arts' or similar. Alternatively, check WordPress admin under Appearance > Themes.Affected if The Designthemes Crafts & Arts theme is present in the WordPress installation
-
Check the installed theme versionOpen the theme's style.css file (usually in wp-content/themes/designthemes-crafts-arts/style.css) and look for the 'Version:' header in the file comments. Compare this version to any version ranges provided by the vendor.Affected if The installed version falls within an affected version range or cannot be determined
-
Search for unsafe deserialization in theme filesUse grep or a file search tool to locate 'unserialize(' calls within the theme directory: grep -r "unserialize(" wp-content/themes/designthemes-crafts-arts/Affected if The theme contains unserialize() calls processing data
-
Determine if user input reaches unserialize()Examine any identified unserialize() calls to trace whether $_GET, $_POST, $_COOKIE, or other user-supplied data is passed directly or indirectly to the unserialize() function.Affected if User-controlled data is deserialized without sanitization
-
Check if theme features accepting user data are enabledIdentify theme features or shortcodes that accept user input (contact forms, submission forms, custom fields) and verify if they are in use on the site.Affected if Features that could deliver malicious serialized payloads are active
A user is affected if the Designthemes Crafts & Arts theme is installed, contains unsafe unserialize() calls handling user input, and the installed version matches an affected range.

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 deserialization (unserialize()) with safe alternatives like json_decode() for any user-supplied data, or implement a whitelist approach. If a patched version is available from the vendor, upgrade immediately.
