Show Stock Quotes by 99 Robots Security & Risk Analysis

The "show-stock-quotes" plugin version 2.3.2 demonstrates a strong adherence to several security best practices. The static analysis reveals no discernible attack surface in terms of AJAX handlers, REST API routes, shortcodes, or cron events, which is a significant positive. Furthermore, the absence of dangerous functions, file operations, and external HTTP requests mitigates common attack vectors. The consistent use of prepared statements for all SQL queries is commendable and prevents SQL injection vulnerabilities. However, a notable concern is the low percentage of properly escaped output (15%), indicating a potential for Cross-Site Scripting (XSS) vulnerabilities if user-supplied data or dynamic content is not adequately sanitized before display. The plugin also lacks nonce and capability checks, which could be exploited in conjunction with other vulnerabilities to perform unauthorized actions. The vulnerability history shows no recorded CVEs, suggesting a relatively secure past, but this should not be a sole determinant of current security. The bundled jQuery v1.11.1 is outdated and may contain known vulnerabilities, although the static analysis did not directly identify exploitable issues from it. Overall, while the plugin has a clean attack surface and good SQL practices, the unescaped output and lack of critical security checks on potential entry points are significant weaknesses that require immediate attention.
