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 CRM Perks WP Gravity Forms Keap/Infusionsoft gf-infusionsoft allows Object Injection.This issue affects WP Gravity Forms Keap/Infusionsoft: from n/a through <= 1.2.3.
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 stemming from unsafe deserialization of untrusted data in the WP Gravity Forms Keap/Infusionsoft plugin (gf-infusionsoft). The flaw allows an attacker to inject malicious PHP objects, potentially leading to arbitrary code execution or other deserialization-based attacks.

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 the plugin is installedCheck if the gf-infusionsoft or gravityforms-infusionsoft directory exists in your WordPress plugins folder (wp-content/plugins/)Affected if The plugin directory is present on the server
-
Identify the installed versionOpen the main plugin PHP file (usually gf-infusionsoft.php or index.php) in the plugin directory and locate the Version header in the plugin comment block, or check a version.php file if presentAffected if The version number found is lower than 1.2.4 (e.g., 1.2.3, 1.2.2, etc.)
-
Verify the vulnerability is reachableThe vulnerability is in the plugin's PHP code that handles deserialized data. Check if the plugin is active in WordPress admin under Plugins > Installed PluginsAffected if The plugin is activated and accessible via the WordPress site
-
Look for signs of exploitation attemptsSearch WordPress access logs and error logs for unusual PHP serialized data patterns (e.g., O:), or examine any recent files modified in the wp-content/uploads/ or plugin directories for suspicious PHP codeAffected if Unusual serialized PHP object patterns appear in logs or unexpected PHP files exist in uploads directory
You are affected if the gf-infusionsoft plugin is installed with a version lower than 1.2.4 and the plugin is active on your WordPress site.

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 dataUpdate the WP Gravity Forms Keap/Infusionsoft plugin to the latest patched version once released, or implement proper input validation and sanitize all data before deserialization to prevent object injection.
