JS Currency Converter Security & Risk Analysis

The 'js-currency-converter' v1.2 plugin exhibits a mixed security posture. On the positive side, it has no recorded vulnerabilities (CVEs) and no critical findings in taint analysis, suggesting a history of relatively secure development. The static analysis also shows no direct database queries without prepared statements and no file operations, which are common vectors for attacks. However, several significant concerns emerge from the code analysis. The absence of any nonce or capability checks for its single shortcode is a major weakness, as it represents an unprotected entry point. Furthermore, a substantial portion (73%) of its output is not properly escaped, posing a risk of Cross-Site Scripting (XSS) vulnerabilities, especially if user-supplied data is involved in these outputs. The use of a bundled library, Select2, also warrants attention, as outdated bundled libraries can introduce vulnerabilities.
