Ultimate Loan & Mortgage Calculator Security & Risk Analysis

The 'ultimate-loan-mortgage-calculator' plugin version 1.2.0 exhibits a mixed security posture. On the positive side, it demonstrates good practices in database interaction, using prepared statements exclusively for all SQL queries and a high percentage of properly escaped output. The absence of known CVEs and a clean vulnerability history suggest a generally well-maintained codebase regarding external exploits. However, significant concerns arise from its attack surface. A substantial portion of its entry points, specifically all four AJAX handlers, lack authentication checks. This creates a substantial risk of unauthorized access or malicious manipulation of plugin functionalities if these handlers are exploitable. While taint analysis shows no critical or high-severity unsanitized flows, the potential for an attacker to trigger these handlers without proper authorization is a primary security weakness.
