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 · unedited
Deserialization of Untrusted Data vulnerability in AncoraThemes Jardi jardi allows Object Injection.This issue affects Jardi: from n/a through <= 1.7.2.

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 confidence

A PHP Object Injection vulnerability exists in the Jardi theme where untrusted data is deserialized without proper validation. This allows attackers to inject arbitrary PHP objects into the application, potentially leading to remote code execution, file operations, or other malicious actions depending on the available gadget chains within the application.

MitigationReplace all instances of unsafe PHP deserialization (unserialize()) with safe alternatives such as json_decode() for JSON data, implement strict input validation, and apply principle of least privilege to prevent exploitation.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Jardi theme installation
    Locate the Jardi theme folder in your web application's theme directory (commonly wp-content/themes/jardi or similar path depending on your CMS/platform)
    Affected if The Jardi theme folder exists in your themes directory
  2. Identify theme version
    Check theme version file (typically version.php, style.css header, or theme.json) and compare the version number against any documented affected versions
    Affected if Installed version falls within an affected version range or is unknown/older than patched versions
  3. Locate unsafe deserialization
    Search all PHP files within the Jardi theme directory for the unserialize() function usage, especially in files handling user requests or data processing
    Affected if Theme contains unserialize() calls that process input data
  4. Verify input reaches deserialization
    Examine the code paths leading to unserialize() calls to determine if data originates from user input sources such as GET/POST parameters, cookies, or database fields
    Affected if Untrusted or user-supplied data is passed directly to unserialize() without validation
  5. Confirm gadget chain availability
    Review application for presence of PHP classes that could be exploited via object injection (check for file operations, command execution, or magic methods like __wakeup, __destruct)
    Affected if Application contains exploitable PHP classes usable as gadget chains

Your environment is affected if the Jardi theme is installed AND contains unserialize() calls that process untrusted input from user-controllable sources.

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.
