Summary
The file mexcel.php in Vfront 0.99.52 contains a vulnerability due to insecure deserialization of user-controlled input. The unserialize function is called on base64-decoded $_POST['mexcel'] data without validation or the allowed_classes option, allowing an attacker to inject arbitrary PHP objects. This can lead to remote code execution, SQL injection, path traversal, or denial of service.
Risk Assessment
The organization risks server compromise, data breaches, or service disruption. An attacker can exploit available classes in Vfront or its dependencies to achieve remote code execution.
Recommendation
Immediately update Vfront to the latest patched version. If an update is not possible, replace the unserialize call with a safe function like json_decode or use the allowed_classes option with an empty array.

The Super Forms plugin for WordPress up to version 6.3.316 contains an arbitrary directory deletion vulnerability. This is due to insufficient validation of attacker-controlled JSON fields and an ineffective ABSPATH guard that can be easily bypassed. An unauthenticated attacker can recursively delete arbitrary directories on the server, including the WordPress root directory, provided the administrator has enabled the 'Delete files from server after form submissions' setting.

Original NVD description (English source)
The file mexcel.php in the Vfront 0.99.52 codebase contains a vulnerable call to unserialize(base64_decode($_POST['mexcel'])), where $_POST['mexcel'] is user-controlled input. This input is decoded from base64 and deserialized without validation or use of the allowed_classes option, allowing an attacker to inject arbitrary PHP objects. This can lead to malicious behavior, such as Remote Code Execution (RCE), SQL Injection, Path Traversal, or Denial of Service, depending on the availability of exploitable classes in the Vfront codebase or its dependencies.
