Iframely – WP media embeds, cards and blocks Security & Risk Analysis

The iframely plugin v1.1.6 exhibits a generally good security posture based on the provided static analysis. The absence of known CVEs and a clean vulnerability history suggest a well-maintained codebase. The plugin also demonstrates strong adherence to several security best practices, including the complete use of prepared statements for SQL queries and the presence of nonce and capability checks, which significantly reduce the risk of common web attacks.

However, there are areas for improvement. A notable concern is the low percentage of properly escaped output (13%). This could potentially lead to Cross-Site Scripting (XSS) vulnerabilities if user-supplied data is not handled meticulously before being displayed. While the attack surface is small and appears to be protected, the lack of taint analysis data is a limitation, as it prevents a thorough assessment of potential data flow vulnerabilities. The single external HTTP request should also be monitored, though it's not inherently a risk without further context.

Overall, iframely v1.1.6 is a relatively secure plugin, with its main weakness lying in output escaping. The plugin's history of no vulnerabilities is a strong positive indicator. Addressing the output escaping concerns and potentially incorporating more comprehensive taint analysis in future audits would further solidify its security.
