iChart – Easy Charts and Graphs Security & Risk Analysis

The "ichart" v2.1.4 plugin exhibits a generally good security posture with several positive indicators. Notably, there are no identified taint flows, no dangerous functions used, and all SQL queries are properly prepared. The plugin also incorporates a commendable number of capability checks and nonce checks, contributing to a robust defense against common attacks. Furthermore, the absence of unpatched CVEs in its history is a strong positive sign, suggesting active maintenance and prompt security patching.

However, the plugin's static analysis does reveal some areas for improvement. While the overall output escaping is at 78%, this still leaves 22% of outputs potentially unescaped, which could present a cross-site scripting (XSS) risk, especially given that XSS has been a historical vulnerability type for this plugin. The presence of two external HTTP requests also warrants attention, as these can sometimes be exploited if not handled securely. The plugin's vulnerability history, while currently clean, did include a past medium-severity vulnerability related to improper neutralization of input, reinforcing the need for vigilant output sanitization.

In conclusion, "ichart" v2.1.4 demonstrates strong foundational security practices, particularly in its handling of SQL and authentication. The primary concern lies in the potential for unescaped output, a historical weakness that should be addressed to mitigate XSS risks. Continued vigilance regarding external requests and ongoing monitoring of its vulnerability history will be crucial for maintaining its security.
