Sliced Invoices & Formidable Forms Security & Risk Analysis

The "sliced-invoices-formidable-forms" plugin v1.0.2 exhibits a concerning security posture due to its limited attack surface being entirely unprotected. Both AJAX handlers lack authentication checks, creating a significant entry point for malicious actors. While the static analysis did not reveal dangerous functions, raw SQL queries, or critical taint flows, the high percentage of improperly escaped output (68%) suggests a risk of Cross-Site Scripting (XSS) vulnerabilities. The complete absence of nonce checks and capability checks further exacerbates these risks, as there are no mechanisms to verify user intent or permissions for these unprotected entry points. The plugin's vulnerability history is clean, with no recorded CVEs. This could indicate either a well-developed plugin or that it hasn't been extensively targeted or audited. However, relying solely on this history is imprudent given the identified code weaknesses. The strengths lie in the absence of file operations, external HTTP requests, and the fact that a majority of SQL queries use prepared statements. Nevertheless, the unprotected AJAX handlers and poor output escaping present immediate and actionable security concerns.
