Invoize – PDF Invoices, Packing Slips, Quotations & WooCommerce Invoicing Security & Risk Analysis

The 'invoize' v1.21.0 plugin exhibits a generally strong security posture based on the provided static analysis. It demonstrates good practices by implementing prepared statements for all SQL queries and a high percentage of properly escaped outputs. The absence of known CVEs and vulnerabilities in its history is a significant positive indicator, suggesting a commitment to security or a lack of exploitable weaknesses discovered thus far. The minimal attack surface with no identified unprotected entry points further strengthens its security. However, the presence of 21 'unserialize' calls is a notable concern. While the data doesn't explicitly show unsanitized taint flows originating from these calls, 'unserialize' is inherently risky as it can lead to object injection vulnerabilities if the serialized data originates from an untrusted source and is not properly validated. The plugin also uses bundled libraries, which, if not kept up-to-date, could introduce vulnerabilities, although specific version information for all bundled libraries beyond Freemius v1.0 is not provided.
