Is Code Markup Safe to Use in 2026?
Generally Safe
Score 85/100Code Markup has no known CVEs and is actively maintained. It's a solid choice for most WordPress installations.
The plugin 'code-markup' v1.3 demonstrates an exceptionally strong security posture based on the provided static analysis results. The absence of any identified attack surface, including AJAX handlers, REST API routes, shortcodes, and cron events, significantly reduces the potential for external exploitation. Furthermore, the code shows adherence to secure coding practices, with no dangerous functions, all SQL queries utilizing prepared statements, and all outputs being properly escaped. The lack of file operations and external HTTP requests further minimizes risk. The plugin also has no recorded vulnerability history, which is a positive indicator of its past security performance.
However, the complete absence of nonce checks and capability checks across all potential entry points (though zero are identified) represents a theoretical concern. While the current attack surface is zero, any future additions or unforeseen interactions could potentially be exposed if these fundamental security mechanisms are not implemented by default. The lack of any identified taint flows is also noteworthy, suggesting that the code is either very simple or very robust against common injection vulnerabilities.
In conclusion, 'code-markup' v1.3 appears to be a highly secure plugin. Its strengths lie in its minimal attack surface and strict adherence to secure coding practices for the features it does implement. The primary, albeit theoretical, weakness is the lack of any demonstrated security checks like nonces or capabilities, which could become relevant if the plugin's functionality expands. Given the current data, the risk associated with this plugin is very low.
