CVE-2025-68899
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 Vivagh vivagh allows Object Injection.This issue affects Vivagh: from n/a through <= 2.4.
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 confidenceThis is a PHP Object Injection vulnerability in the Vivagh WordPress theme. The theme deserializes untrusted data without proper validation, allowing an attacker to craft malicious serialized PHP objects that could lead to remote code execution, file manipulation, or database compromise depending on available gadgets in the application.

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 Vivagh theme is installedNavigate to wp-content/themes/ in your WordPress installation and check for a folder named 'vivagh' or similar. Alternatively, go to Appearance > Themes in WordPress admin and look for the Vivagh theme.Affected if The vivagh theme folder exists in the themes directory
-
Identify installed Vivagh theme versionCheck the style.css file within the Vivagh theme folder for the 'Version:' header, or look in the theme's main PHP file for a version constant. You can also check via WordPress admin at Appearance > Themes > Theme Details.Affected if The reported version is 2.4 or lower (including any 2.x version below 2.4)
-
Locate unsafe unserialize() calls in theme codeSearch all PHP files within the Vivagh theme folder for instances of 'unserialize(' where the input comes from user-controlled sources like $_GET, $_POST, $_COOKIE, or database fields. Use grep or a code editor to scan theme files.Affected if An unserialize() call exists that processes data from untrusted sources without prior validation
-
Verify theme is activeCheck WordPress admin at Appearance > Themes to confirm the Vivagh theme is currently activated. Also check if the theme handles form submissions, AJAX requests, or API endpoints that could pass user data to deserialization functions.Affected if The theme is active and processing requests that could reach the vulnerable deserialization code
You are affected if the Vivagh theme is installed at version 2.4 or lower AND your site processes requests that trigger the unsafe unserialize() call with untrusted input.
Generated from the published advisory. Verify against your own configuration.
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 safer alternatives like json_decode, implement whitelist validation for allowed classes if deserialization is required, and audit the theme for additional deserialization points and available PHP gadget chains.
