Is MainWP Post SMTP Extension – Easily Manage WP SMTP Setup for All Sites in One Place Safe to Use in 2026?
Generally Safe
Score 100/100MainWP Post SMTP Extension – Easily Manage WP SMTP Setup for All Sites in One Place has no known CVEs and is actively maintained. It's a solid choice for most WordPress installations.
The post-smtp-for-mainwp plugin v1.0.5 exhibits a generally strong security posture with notable strengths in its handling of SQL queries and output escaping. The plugin utilizes prepared statements for all its SQL queries, significantly reducing the risk of SQL injection. Furthermore, a high percentage of output is properly escaped, which is crucial for preventing cross-site scripting (XSS) vulnerabilities.
However, a significant concern arises from its attack surface. The analysis reveals one REST API route that lacks permission callbacks. This unprotected entry point could potentially be exploited by unauthenticated users, leading to unauthorized actions or information disclosure, depending on the functionality exposed by that route.
The plugin's vulnerability history is clean, with no known CVEs recorded. This absence of historical vulnerabilities, combined with the good coding practices observed in SQL and output handling, suggests a codebase that is actively maintained and security-conscious. Despite the single unprotected REST API route, the overall security outlook is positive, with the primary area for improvement being the hardening of its REST API endpoints.
