Push Notifications for WP – Self Hosted Web Push Notifications Security & Risk Analysis

The "push-notification" plugin v1.48 presents a generally good security posture with a notable absence of known historical vulnerabilities and a robust implementation of security best practices in its code. The plugin demonstrates strong adherence to WordPress security standards by implementing nonce checks and capability checks on all its AJAX handlers and having no unprotected entry points. Furthermore, the SQL query preparation is reasonably high, with 75% using prepared statements, and a significant majority of output is properly escaped, mitigating common injection and XSS risks. The presence of bundled Select2, while not inherently a security flaw, is a point to monitor for potential outdated versions in future analyses. However, the taint analysis reveals two flows with unsanitized paths, which, despite not being classified as critical or high severity in this report, represent a potential risk. These unsanitized paths should be investigated and addressed to ensure complete security. The plugin's history of zero CVEs is highly encouraging and suggests a diligent development team. Overall, the plugin is well-secured, with the taint analysis being the primary area requiring attention to achieve a truly secure state.
