Is Flexible PDF Safe to Use in 2026?
Generally Safe
Score 85/100Flexible PDF has no known CVEs and is actively maintained. It's a solid choice for most WordPress installations.
The "flexible-pdf" plugin v1.0.1 demonstrates a generally positive security posture with no recorded vulnerabilities in its history. The static analysis reveals no dangerous functions, SQL queries are exclusively prepared, and there are no identified taint flows with unsanitized paths. This suggests a good understanding of secure coding principles regarding direct data manipulation and common web vulnerabilities. However, the analysis does highlight some areas for improvement. Notably, only 54% of output is properly escaped, which could lead to Cross-Site Scripting (XSS) vulnerabilities if user-supplied data is not handled rigorously throughout the entire output process. Additionally, the presence of a single external HTTP request without specific details raises a potential concern, as it could be a vector for various attacks if the external resource is compromised or malicious.
Key Concerns
- Output escaping is only 54% proper
- One external HTTP request identified
