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 · high confidenceThis is an unauthenticated PHP Object Injection vulnerability in the Broadcast Live Video WordPress plugin versions prior to 7.1.3. The flaw allows remote attackers to inject malicious PHP objects via unserialization of untrusted input, potentially leading to remote code execution depending on available gadget chains 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 plugin installationCheck if the Broadcast Live Video plugin is installed in the WordPress plugins directory (wp-content/plugins/) or via WordPress admin under Plugins > Installed Plugins. Look for 'Broadcast Live Video' or similar naming.Affected if The plugin is present in the WordPress installation.
-
Check installed plugin versionIn WordPress admin, go to Plugins > Installed Plugins and find the Broadcast Live Video plugin. Click on the plugin name to view version details. Alternatively, check the plugin's main PHP file header for 'Version:' comment or check the readme.txt file.Affected if The version displayed is lower than 7.1.3.
-
Verify vulnerable code path existsExamine the plugin's PHP files for unserialize() calls that process user input without authentication. Common entry points include AJAX actions (wp_ajax_*), init hooks, or form handlers. Search for patterns like 'unserialize($_POST[', 'unserialize($_GET[', or 'unserialize($_REQUEST'.Affected if The plugin contains unserialize() calls processing unauthenticated input from $_POST, $_GET, or $_REQUEST arrays.
-
Review server access logsCheck web server access logs (Apache/nginx) for unusual requests to the plugin's AJAX endpoints or form processing scripts. Look for serialized PHP objects in POST data or query strings. Logs are typically in /var/log/apache2/access.log or /var/log/nginx/access.log.Affected if Log entries contain serialized PHP object payloads targeting the plugin's endpoints.
A user is affected if the Broadcast Live Video plugin is installed with a version lower than 7.1.3 and contains unserialize() calls processing unauthenticated user input.
