Custom Guest Authors Security & Risk Analysis

The custom-guest-authors plugin v2.3.1 demonstrates several good security practices, including a lack of identifiable attack surface points through AJAX, REST API, shortcodes, and cron events. The code also shows a high percentage of properly escaped output and a reasonable number of nonce and capability checks. This suggests the developers have some awareness of common WordPress security vulnerabilities.

However, a significant concern arises from the static analysis indicating 100% of SQL queries are not using prepared statements. This is a substantial risk, as it opens the door to SQL injection vulnerabilities, especially if any of the input data used in these queries is not rigorously sanitized. The taint analysis also identified one flow with unsanitized paths, which, while not classified as critical or high severity, warrants attention as it represents a potential pathway for attackers.

The absence of any recorded vulnerabilities in its history is a positive sign, implying a generally secure past. Nevertheless, the static analysis findings, particularly the raw SQL queries, point to a potential weakness that could be exploited. The overall security posture is therefore a mix of good practices and a critical oversight in database interaction.
