CVE-2025-52828
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 Red Art redart allows Object Injection.This issue affects Red Art: from n/a through <= 3.8.
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 Red Art WordPress theme <= 3.8 contains a PHP Object Injection vulnerability caused by unsafe deserialization (unserialize()) of untrusted data. This allows unauthenticated attackers to inject malicious PHP objects, potentially leading to remote code execution if suitable gadget chains exist in the application or 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.
-
Identify if Red Art theme is installedCheck the WordPress themes directory (wp-content/themes/) for a folder named 'red-art', 'redart', or similar. List all installed themes and look for Red Art.Affected if The Red Art theme folder exists in the themes directory.
-
Check the installed versionOpen the theme's style.css file (usually in wp-content/themes/red-art/style.css) and look for the 'Version:' header in the file comments. Alternatively, check theme.json for a version field.Affected if The reported version is 3.8 or lower (or if no version is found and the theme appears to be Red Art).
-
Locate unserialize() calls in theme filesSearch all PHP files in the theme directory for the pattern 'unserialize(' using grep or a file search tool. For example: grep -r "unserialize(" wp-content/themes/red-art/Affected if Any unserialize() call is found within the theme's PHP files.
-
Check if unserialize processes user inputExamine each unserialize() call found. Look for it being called directly on $_GET, $_POST, $_REQUEST, or any input derived from user requests (e.g., $_GET['data'], $_POST['var']).Affected if A unserialize() call is directly using $_GET, $_POST, $_REQUEST, or similar user-supplied data as its argument.
-
Verify the attack surface is reachableDetermine if the file containing the vulnerable unserialize() is accessible without authentication. Check if the function is hooked to an action or filter that runs for unauthenticated users (e.g., init, wp_ajax, wp_ajax_nopriv, template_redirect).Affected if The vulnerable code is accessible to unauthenticated (not-logged-in) users.
You are affected if the Red Art theme is installed with version 3.8 or lower AND contains an unserialize() call that processes untrusted input from users without authentication.

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 dataIdentify and remediate all instances of unserialize() calls on user-supplied input within the theme; replace with safe serialization methods like json_encode/json_decode. If a patched version is available, upgrade to the latest version immediately.
