Is Code Syntax Highlighter Safe to Use in 2026?
Generally Safe
Score 85/100Code Syntax Highlighter has no known CVEs and is actively maintained. It's a solid choice for most WordPress installations.
The "code-syntax-highlighter" plugin v1.0.0 presents a mixed security posture. While the absence of recorded CVEs and a lack of critical taint flows are positive indicators, the static analysis reveals significant areas for improvement. The most pressing concern is the presence of two AJAX handlers that lack authentication checks. This creates a direct attack surface where unauthenticated users could potentially trigger unintended functionality within the plugin, leading to various security issues depending on the implementation of these handlers.
The code analysis also highlights a low percentage (26%) of properly escaped output. This indicates a risk of Cross-Site Scripting (XSS) vulnerabilities. If user-supplied data is processed and displayed without adequate sanitization, it could be exploited to inject malicious scripts into the website.
While the plugin has no known vulnerability history, this can be attributed to its current version and potentially limited exposure. However, the static analysis findings, particularly the unauthenticated AJAX endpoints and poor output escaping, suggest that future vulnerabilities are a distinct possibility if not addressed. The plugin demonstrates some good practices like using prepared statements for SQL queries and having capability checks, but these are overshadowed by the readily exploitable entry points.
