CVE-2024-49222
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 AmentoTech Private Limited WPGuppy wpguppy-lite allows Object Injection.This issue affects WPGuppy: from n/a through <= 1.1.0.
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 confidencePHP Object Injection vulnerability in WPGuppy Lite WordPress plugin allows unauthenticated attackers to deserialize untrusted data, potentially leading to remote code execution through crafted PHP objects.

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 WPGuppy Lite is installed and activeLog in to WordPress admin panel and navigate to Plugins > Installed Plugins. Locate WPGuppy Lite in the list and verify its status shows as 'Active'. Alternatively, check the /wp-content/plugins/ directory for the wpguppy-lite folder and inspect the main plugin file header for version information.Affected if The plugin is installed and active, making the vulnerable code accessible to attackers.
-
Identify the installed plugin versionIn WordPress admin, click on the WPGuppy Lite plugin to view its details, which typically displays the version number. Alternatively, open the main plugin file (usually wpguppy-lite.php) and locate the 'Version' header in the plugin comment block.Affected if The installed version falls within the vulnerable range and has not been patched.
-
Check if unserialize() is used on user-supplied dataInspect the plugin source code in /wp-content/plugins/wpguppy-lite/ for calls to unserialize() function, particularly those processing $_GET, $_POST, $_REQUEST, or cookie values without sanitization. Use grep or a code editor to search for patterns like 'unserialize($_' within the plugin directory.Affected if The plugin deserializes untrusted input from external sources without validation.
-
Verify AJAX and public endpoints are accessibleCheck the plugin registers AJAX hooks (admin-ajax.php or wp_ajax_) and public-facing handlers. Test whether the vulnerable endpoint responds to unauthenticated requests by examining the plugin code for add_action calls with 'wp_ajax_nopriv_' or 'wp_ajax_' hooks.Affected if The vulnerable deserialization is reachable without authentication.
-
Review access logs for exploitation attemptsExamine web server access logs (Apache error.log, Nginx access.log) for requests to WPGuppy Lite endpoints containing serialized PHP objects (O:*, a:*, or base64-encoded serialized strings). Search for patterns like 'wpguppy' in URL paths with suspicious parameter values.Affected if Logs show incoming requests with serialized payloads targeting the plugin.
A user is affected if WPGuppy Lite is active, uses insecure unserialize() on external input, and the installed version has not been patched against this PHP Object Injection flaw.

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.
dbcve · scopedUpgrade to a patched version of WPGuppy Lite; if unavailable, disable or remove the plugin until a fix is released. Implement WAF rules as interim protection.
Latest available version of WPGuppy/WPGuppy Lite (newer than 1.1.0)
- Check WordPress admin panel for wpguppy-lite plugin updates
- Navigate to Plugins > Installed Plugins > WPGuppy Lite
- If an update is available, update to the latest version
- If no update is available from WordPress repository, contact the vendor (AmentoTech Private Limited) directly for the patched version
- Verify the plugin has been updated to a version newer than 1.1.0 after updating
