CyberRota Analysis

AI-Generated

The WS Form LITE plugin for WordPress is critically vulnerable to PHP Object Injection due to the deserialization of untrusted input from form submission meta values in versions up to 1.10.80. This flaw allows unauthenticated attackers to potentially exploit the vulnerability if a vulnerable plugin or theme containing a PHP Object Pollution (POP) chain is also installed, which could lead to severe actions such as arbitrary file deletion, sensitive data retrieval, or remote code execution. WordPress administrators using this plugin should prioritize immediate updates to mitigate the risk.

Original NVD Description

The WS Form LITE – Drag & Drop Contact Form Builder plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.10.80 via deserialization of untrusted input from form submission meta values. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.
