Editorial Calendar Security & Risk Analysis

The "editorial-calendar" plugin version 3.9.2 exhibits a mixed security posture. While it demonstrates good practices such as 100% of SQL queries using prepared statements and a significant number of capability checks (8), there are notable areas of concern. The presence of 7 AJAX handlers, with 3 of them lacking proper authentication checks, significantly expands the attack surface and presents a direct risk of unauthorized actions.

The static analysis also reveals that only 23% of output is properly escaped, indicating a potential for Cross-Site Scripting (XSS) vulnerabilities, especially when combined with the unsanitized path flow identified in the taint analysis. Although no critical or high severity taint flows were found, the single unsanitized path flow is still a concern.

The plugin's vulnerability history, with 4 known CVEs and a recent one in late 2025, points to a recurring pattern of security weaknesses, including missing authorization and XSS. The presence of high and medium severity vulnerabilities in the past, even if currently unpatched ones are zero, suggests a need for more robust security development practices. In conclusion, while the plugin has some strengths, the unprotected AJAX handlers and the high percentage of unescaped output are significant risks that require immediate attention.
