Today's Date Inserter Security & Risk Analysis

The "todays-date-inserter" plugin v1.2.1 exhibits a mixed security posture. On the positive side, the plugin demonstrates good practices by having no dangerous functions, no raw SQL queries, and no file operations or external HTTP requests. The limited attack surface, consisting of a single shortcode, is also a strength. However, significant concerns arise from the code signals and vulnerability history. A substantial portion of output (73%) is not properly escaped, creating a significant risk of Cross-Site Scripting (XSS) vulnerabilities. Furthermore, the absence of nonce checks and capability checks on its single entry point (the shortcode) means any user, regardless of their role, could potentially trigger unintended actions or inject malicious code if the shortcode's output is not handled securely by the theme or other plugins. The vulnerability history reveals a past medium-severity XSS vulnerability that is currently unpatched, indicating a recurring issue with input sanitization and output escaping. This unpatched vulnerability, combined with the high rate of unescaped output, suggests a pattern of incomplete security patching and ongoing risks.

In conclusion, while the plugin avoids common pitfalls like raw SQL and dangerous functions, the high rate of unescaped output and the presence of an unpatched XSS vulnerability are critical weaknesses. The lack of security checks on the shortcode further exacerbates these risks. Users should exercise caution and prioritize updating or replacing this plugin, especially given the unpatched vulnerability.
