Correios Automático – Rastreio, Frete, Etiqueta, Declaração e Devolução Security & Risk Analysis

The "infixs-correios-automatico" v1.7.1 plugin exhibits a generally good security posture with several strong practices in place. The absence of dangerous functions, the exclusive use of prepared statements for SQL queries, and a high percentage of properly escaped output are significant strengths. Furthermore, the lack of known CVEs and no recorded vulnerabilities in its history suggest a history of responsible development and maintenance.

However, there are specific concerns that warrant attention. The plugin exposes 2 AJAX handlers without authentication checks, creating a potential attack surface for unauthorized actions. While taint analysis shows no unsanitized paths, the presence of unprotected entry points is a notable risk. The plugin also makes a relatively high number of external HTTP requests (10), which, while not inherently a vulnerability, can be a vector for other attacks if the remote endpoints are compromised or if the plugin does not properly validate the responses.

In conclusion, the plugin has a solid foundation with no critical or high-severity historical vulnerabilities and good internal coding practices. The primary area of concern lies in the unprotected AJAX endpoints. Addressing these unprotected entry points and ensuring robust input validation for external requests would significantly enhance its security. The absence of known vulnerabilities is a positive indicator, but vigilance regarding the identified entry points is crucial.
