Spirit Liturgický kalendár Security & Risk Analysis

The spirit-liturgicky-kalendar plugin v1.4 exhibits a generally positive security posture, with no recorded vulnerabilities or critical code signals indicating immediate threats. The absence of dangerous functions, raw SQL queries, and file operations suggests a cautious approach to sensitive operations. The use of prepared statements for the single SQL query is a strong security practice. However, the analysis reveals significant areas for improvement. A concerningly low 37% of outputs are properly escaped, potentially exposing the plugin to cross-site scripting (XSS) vulnerabilities. Furthermore, the complete lack of nonce and capability checks on any entry points, including a cron event, presents a substantial risk. This means that these entry points can be triggered by unauthenticated or unauthorized users, opening the door for various attacks. The plugin's history of no vulnerabilities could indicate either genuine good security or simply a lack of thorough historical auditing and potential for undiscovered issues. While the plugin avoids common pitfalls, the identified weaknesses in output escaping and access control require immediate attention to mitigate potential security risks.
