Multiple Shipping Options for WooCommerce Security & Risk Analysis

This plugin exhibits a concerning security posture due to a large number of unprotected entry points. With 26 AJAX handlers and 1 REST API route lacking authentication or permission checks, the attack surface is entirely exposed. This significantly increases the risk of unauthorized access and malicious manipulation of plugin functionality. While the code analysis shows no direct use of dangerous functions and a moderate percentage of SQL queries using prepared statements, the absence of nonces and capability checks on these numerous entry points is a critical oversight. The taint analysis revealing two high-severity flows with unsanitized paths further highlights potential vulnerabilities where user-controlled data could be misused. The lack of any recorded vulnerabilities in its history is a positive indicator of past development quality, but it does not mitigate the immediate risks identified in the current code analysis.
