Is APH Syntax Highlighter Safe to Use in 2026?
Generally Safe
Score 85/100APH Syntax Highlighter has no known CVEs and is actively maintained. It's a solid choice for most WordPress installations.
The "aph-syntax-highlighter" plugin version 1.2.2 presents a mixed security posture. On the positive side, there are no recorded vulnerabilities (CVEs) and the plugin demonstrates good practices regarding SQL queries, exclusively using prepared statements. Furthermore, taint analysis shows no critical or high-severity flows, indicating that sensitive data is likely not being mishandled in critical ways within the analyzed code paths. However, significant concerns arise from the static analysis. The plugin exposes a notable attack surface with two AJAX handlers, one of which lacks any authentication checks. This unprotected entry point is a primary security risk. Additionally, a substantial proportion (0%) of outputs are not properly escaped, creating a high risk of Cross-Site Scripting (XSS) vulnerabilities if user-supplied data is ever processed and rendered by these outputs. The lack of capability checks on any entry points further exacerbates the risks associated with these unprotected or improperly handled inputs.
Key Concerns
- AJAX handler without auth checks
- No proper output escaping detected
- No capability checks on entry points
