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 themesflat Themesflat Elementor themesflat-elementor allows Object Injection.This issue affects Themesflat Elementor: from n/a through <= 1.0.1.

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

This is a PHP Object Injection vulnerability in the Themesflat Elementor WordPress theme. The theme deserializes untrusted data without proper sanitization, allowing attackers to inject and instantiate arbitrary PHP objects. Successful exploitation can lead to remote code execution if suitable 'gadget chains' exist in the application or loaded libraries.

MitigationReplace unsafe unserialize() calls with json_encode/json_decode or other safe serialization methods, validate all input before deserialization, and update to a patched version if available.

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 Themesflat Elementor theme is installed
    Navigate to WordPress dashboard > Appearance > Themes, or check the /wp-content/themes/ directory for a themesflat-elementor folder
    Affected if The themesflat-elementor theme folder exists in the WordPress themes directory
  2. Identify the installed theme version
    Check the theme's style.css file in /wp-content/themes/themesflat-elementor/ for the 'Version:' header, or view theme details in WordPress admin under Appearance > Themes
    Affected if The version number found is within or below the affected version range (check against any published patched version)
  3. Locate unsafe deserialization calls in theme code
    Search theme PHP files for 'unserialize(' calls, particularly in files handling user input, AJAX endpoints, or AJAX-like functionality. Use grep or similar: grep -r "unserialize" /wp-content/themes/themesflat-elementor/
    Affected if unserialize() calls are found that process input without prior sanitization (e.g., $_POST, $_GET, $_REQUEST)
  4. Identify entry points for untrusted data
    Review PHP files containing unserialize() to see if they accept data from $_POST, $_GET, $_REQUEST, or HTTP headers without validation
    Affected if The unserialize() function processes data directly from user-supplied input sources without validation
  5. Check for exposed AJAX or admin endpoints
    Examine the theme's includes files for action hooks (add_action) handling AJAX requests, especially those without capability checks or nonce verification
    Affected if AJAX or admin endpoints exist that invoke the vulnerable deserialization code without proper access controls

A user is affected if the Themesflat Elementor theme is installed with a vulnerable version that contains unserialize() calls processing untrusted input from accessible entry points.
