Headless SSO Plugin for WP Security & Risk Analysis

The "headless-single-sign-on" plugin v1.5 exhibits a mixed security posture. While the plugin has no recorded historical vulnerabilities and demonstrates some good practices like a reasonable number of nonce and capability checks, significant concerns arise from the static analysis. The presence of an unprotected AJAX handler represents a direct entry point that could be exploited without proper authentication or authorization, posing a considerable risk. Furthermore, the high percentage of flows with unsanitized paths, despite the absence of critical or high severity taint flows, suggests a general lack of robust input sanitization, which can lead to unexpected behavior or vulnerabilities if not addressed. The low percentage of properly escaped output is also a notable concern, increasing the risk of cross-site scripting (XSS) vulnerabilities.
