Is Customizer Custom CSS Safe to Use in 2026?
Generally Safe
Score 92/100Customizer Custom CSS has no known CVEs and is actively maintained. It's a solid choice for most WordPress installations.
The static analysis of the "customizer-custom-css" plugin version 1.2.3 indicates a generally good security posture. There are no identified AJAX handlers, REST API routes, shortcodes, or cron events that present an attack surface, and all entry points appear to be protected. The code exhibits strong adherence to secure coding practices with no dangerous functions, 100% of SQL queries using prepared statements, and 100% of output being properly escaped. Furthermore, there are no file operations, external HTTP requests, or any identified taint flows, all of which are positive indicators of security. The plugin also has no known vulnerabilities or CVEs, historical or current, suggesting a history of secure development. However, the complete absence of nonce checks and capability checks is a notable weakness. While the current attack surface is zero, if any functionality were to be added in the future without proper authentication and authorization mechanisms, it could introduce significant risks. This, coupled with the lack of any identified vulnerabilities to date, might suggest either a very limited functionality that doesn't warrant such checks, or a potential blind spot in the plugin's security considerations for future development.
