AC's Mortgage Calculator Security & Risk Analysis

The fc-mortgage-calculator plugin version 2.1 exhibits a generally good security posture based on the provided static analysis. The absence of dangerous functions, raw SQL queries, file operations, and external HTTP requests are all positive indicators. The presence of nonce and capability checks on its single entry point (a shortcode) suggests basic security awareness. However, a significant concern arises from the output escaping, with only 61% of outputs properly escaped. This leaves a substantial portion of user-facing output potentially vulnerable to cross-site scripting (XSS) attacks if the plugin handles user-supplied data in these unescaped outputs. The lack of any reported CVEs or taint analysis findings is encouraging and suggests a history of relative security, but it's crucial not to let the good history lull developers into complacency, especially given the identified output escaping weakness.
