Pricing Table WordPress Plugin – Easy Pricing Tables Security & Risk Analysis

The "easy-pricing-tables" plugin version 4.1.1 exhibits a mixed security posture. While it demonstrates good practices such as using prepared statements for all SQL queries and a relatively high percentage of properly escaped output, several concerns warrant attention. The presence of an unprotected AJAX handler represents a significant entry point that could be exploited without proper authentication, posing a risk of unauthorized actions. The taint analysis revealing four high-severity flows with unsanitized paths indicates potential vulnerabilities where user-controlled data could be manipulated to achieve malicious outcomes, even though no critical severities were flagged.

The plugin's vulnerability history, with six known medium-severity CVEs, predominantly related to Cross-site Scripting (XSS) and Cross-Site Request Forgery (CSRF), suggests a recurring pattern of input validation and output sanitization weaknesses. The fact that there are currently no unpatched vulnerabilities is positive, but the historical trend indicates a need for ongoing vigilance and robust security development. The plugin's strengths lie in its secure database interactions and output escaping, but the unprotected entry points and high-severity taint flows are critical areas of concern that elevate the overall risk profile.
