While the current data suggests an excellent security state, it's important to note that no plugin is entirely risk-free. The limited attack surface, while good, also means there are no discernible points for potential vulnerabilities to manifest. The comprehensive use of security features is a significant strength, indicating developers are prioritizing secure coding.
