Silvasoft boekhouden Security & Risk Analysis

The silvasoft-boekhouden plugin v3.0.5 presents a mixed security posture. While it demonstrates good practices by utilizing prepared statements for all SQL queries and having no bundled libraries or file operations, significant concerns exist in other areas. The presence of one unprotected AJAX handler is a major red flag, providing an immediate entry point for attackers. This is further compounded by the taint analysis revealing two flows with unsanitized paths, both classified as high severity. These flows, coupled with the unprotected AJAX handler, strongly suggest potential for Cross-Site Scripting (XSS) and SQL Injection vulnerabilities, aligning with the plugin's historical vulnerability types.

The plugin's vulnerability history is concerning, with two currently unpatched medium severity CVEs. These past vulnerabilities, specifically XSS and SQL Injection, reinforce the risks identified in the static and taint analyses. The fact that the last vulnerability was in 2025 indicates potential ongoing issues. While the plugin correctly uses prepared statements for SQL, the lack of proper output escaping for 67% of its outputs and the absence of nonce checks on AJAX handlers create further opportunities for exploitation. The overall security posture is weakened by these critical gaps, despite some positive technical implementations.
