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 Beelove beelove allows Object Injection.This issue affects Beelove: from n/a through <= 1.2.6.

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 deserialization of untrusted data vulnerability in the AncoraThemes Beelove WordPress theme (versions up to 1.2.6) allows remote attackers to inject malicious PHP objects, potentially leading to remote code execution depending on available gadget chains in the application environment.

MitigationUpdate to a patched version of Beelove theme when available; if no patch exists, replace with a secure theme alternative. Consider deploying a WAF rule to block deserialization-related attack patterns as a temporary measure.

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. Locate the Beelove theme version
    Access the WordPress admin dashboard under Appearance > Themes and click on the Beelove theme to view its details, or inspect the style.css file in wp-content/themes/beelove/ and look for the version comment in the file header
    Affected if the displayed version is 1.2.6 or any version number lower than 1.2.6
  2. Verify theme installation path
    Navigate to wp-content/themes/beelove/ directory via file manager or FTP and confirm the theme files exist
    Affected if the Beelove theme folder is present in the WordPress installation
  3. Search for unserialize() calls in theme code
    Use a file search tool to scan all PHP files within the beelove theme folder for the presence of unserialize(), unserialize($...), or similar PHP deserialization functions that process external input
    Affected if any PHP file in the theme contains an unserialize() function call that processes user-supplied or external data without prior validation
  4. Identify data entry points
    Review theme PHP files for form handlers, AJAX endpoints, or $_GET/$_POST/$_REQUEST data processing that feeds into deserialization functions
    Affected if the theme accepts serialized data from unauthenticated or authenticated user input and passes it to unserialize()
  5. Test for gadget chain availability
    Examine whether the WordPress installation has plugins or other themes that provide PHP object injection gadget chains that could be chained with this deserialization flaw
    Affected if additional components with exploitable gadget chains are present alongside the vulnerable theme

You are affected if the Beelove theme version is 1.2.6 or earlier AND the theme code contains unserialize() processing untrusted input from users.
