Is Site Editor Classic Features Safe to Use in 2026?
Generally Safe
Score 100/100Site Editor Classic Features has no known CVEs and is actively maintained. It's a solid choice for most WordPress installations.
The "fse-classic" v1.0 plugin exhibits an exceptionally strong security posture based on the provided static analysis and vulnerability history. The absence of any detected entry points, including AJAX handlers, REST API routes, shortcodes, or cron events, significantly limits the potential attack surface. Furthermore, the code demonstrates excellent security practices with zero dangerous functions, all SQL queries using prepared statements, and 100% proper output escaping. The lack of file operations, external HTTP requests, and importantly, missing nonce and capability checks, further reinforce its robust design. The completely clean vulnerability history, with no recorded CVEs, further solidifies this positive assessment. However, the analysis reveals a complete absence of any dynamic testing signals, such as taint analysis flows or even the presence of any functional entry points. While this indicates no *detected* vulnerabilities, it also means the plugin's actual dynamic behavior and interaction points haven't been thoroughly tested for security flaws. This is a theoretical strength rather than a practically proven one.
