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.

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 confidenceA deserialization vulnerability in the WP Funnel Manager WordPress plugin (versions up to 1.4.0) allows unauthenticated attackers to inject malicious PHP objects by supplying untrusted serialized data, potentially leading to remote code execution via known object injection gadgets.

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.
-
Locate WP Funnel Manager plugin filesCheck your WordPress plugins directory (wp-content/plugins/) for a folder named 'wp-funnel-manager' or similar containing the plugin files.Affected if The plugin folder exists in the plugins directory.
-
Read the installed plugin versionOpen the main plugin PHP file (usually wp-funnel-manager.php) or the readme.txt file in the plugin folder and locate the 'Version:' field in the plugin header comment.Affected if The version listed is 1.4.0 or any earlier version (e.g., 1.3.x, 1.2.x, 1.1.x, 1.0.x).
-
Confirm the plugin is activeLog into WordPress admin and go to Plugins > Installed Plugins, or query the wp_options table for the option_name 'active_plugins' to see if the plugin is enabled.Affected if The plugin appears in the active plugins list or option value.
-
Identify unsafe deserialization codeSearch within the plugin directory for calls to unserialize() function, for example using grep: grep -r "unserialize" /path/to/wp-content/plugins/wp-funnel-manager/Affected if Any PHP file in the plugin contains an unserialize() call handling untrusted user input.
If the WP Funnel Manager plugin is installed, active, and running version 1.4.0 or earlier with unserialize() handling external data, the environment is vulnerable to CVE-2025-52761.

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 dataReplace unsafe unserialize() calls with json_decode() for data handling, implement strict allowlist validation for any deserialized classes, and update to the latest patched version of the plugin if available.
