Is SAR Friendly SMTP Safe to Use in 2026?
Generally Safe
Score 100/100SAR Friendly SMTP has no known CVEs and is actively maintained. It's a solid choice for most WordPress installations.
Based on the provided static analysis and vulnerability history, the sar-friendly-smtp plugin v1.2.6 exhibits a strong security posture. The code analysis reveals no dangerous functions, SQL queries are exclusively handled with prepared statements, and all output is properly escaped. Crucially, there are no identified taint flows or file operations, indicating a low risk of code injection or arbitrary file manipulation. The presence of nonce and capability checks on the single identified entry point further reinforces its security. The plugin also boasts a clean vulnerability history with zero known CVEs, suggesting a history of secure development and maintenance. However, it is important to note that the absence of any analysis results in certain categories (like taint analysis or attack surface details) might be due to the plugin's simplicity or limitations in the analysis tool's scope. While the current data points to a secure plugin, continuous vigilance and regular updates are always recommended for any software.
