Post by Weekday Security & Risk Analysis

The "post-by-weekday" plugin version 2.1.0 exhibits a mixed security posture. On the positive side, it demonstrates good practices by avoiding dangerous functions, file operations, and external HTTP requests. The absence of known vulnerabilities in its history is also a positive indicator. However, significant concerns arise from the static analysis. The plugin has one AJAX handler, and critically, this handler lacks any authentication checks, creating a direct entry point for attackers. While taint analysis shows no critical or high severity unsanitized paths, the presence of two flows with unsanitized paths, albeit not reaching critical levels, warrants attention, especially in conjunction with the unprotected AJAX handler. The lack of nonce checks and capability checks on the AJAX handler further exacerbates the risk, as it allows any user to potentially trigger actions without proper verification. The plugin's vulnerability history is clean, suggesting a generally well-maintained codebase in the past, but this cannot compensate for the immediate security flaws identified in the current version's analysis. Overall, while the plugin avoids some common pitfalls, the unprotected AJAX endpoint presents a clear and present danger that requires immediate remediation.
