Is Simpinby Invoice Manager – Billing & Invoicing Safe to Use in 2026?
Generally Safe
Score 100/100Simpinby Invoice Manager – Billing & Invoicing has no known CVEs and is actively maintained. It's a solid choice for most WordPress installations.
The plugin "simpinby-invoice-manager" v1.0.1 demonstrates a strong security posture based on the provided static analysis and vulnerability history. The code exhibits excellent adherence to security best practices, with a high percentage of SQL queries using prepared statements and nearly all output being properly escaped. The presence of numerous nonce and capability checks on its AJAX handlers indicates a proactive approach to access control, and the absence of any reported CVEs further bolsters confidence in its security.
While the static analysis reveals no critical or high severity taint flows and a clean vulnerability history, there are minor areas for consideration. The presence of two file operations, though not inherently problematic, warrants attention to ensure they are not susceptible to path traversal or other file manipulation vulnerabilities. Additionally, the bundling of the dompdf library, while not explicitly flagged as outdated or vulnerable in this report, represents a potential risk if not kept up-to-date in future versions. Overall, this plugin appears to be well-secured, with no immediate critical vulnerabilities identified. Continued vigilance regarding the bundled library and file operations is recommended for long-term security.
