f(x) SSL Security & Risk Analysis
wordpress.org/plugins/fx-sslSimple SSL(HTTPS) Plugin.
Is f(x) SSL Safe to Use in 2026?
Generally Safe
Score 85/100f(x) SSL has no known CVEs and is actively maintained. It's a solid choice for most WordPress installations.
The fx-ssl plugin version 1.1.0 presents a mixed security posture. On the positive side, there are no registered vulnerabilities (CVEs) associated with this plugin, and the static analysis shows no immediate critical or high severity issues. The absence of dangerous functions, file operations, external HTTP requests, and the use of prepared statements for SQL queries are all good security practices. However, there are significant concerns regarding output escaping and the presence of unsanitized paths in taint flows.
The static analysis indicates that only 38% of output is properly escaped. This is a notable weakness, as insufficient output escaping can lead to Cross-Site Scripting (XSS) vulnerabilities, allowing attackers to inject malicious scripts into the website. Additionally, the taint analysis revealed two flows with unsanitized paths. While marked as critical and high severity 0, this still points to potential pathways where user-supplied data could be misused to access or manipulate files or system resources if not handled with proper sanitization and validation.
The plugin's vulnerability history is clean, which is a positive indicator. However, the lack of recorded vulnerabilities could also be due to limited security auditing or the plugin's specific functionality not attracting attacker interest. The significant number of unprotected entry points being zero is excellent. Despite the clean history, the identified weaknesses in output escaping and taint flows warrant attention to prevent potential security incidents.
Key Concerns
- Low output escaping percentage (38%)
- Unsanitized paths in taint flows (2 instances)
