Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Bypasses in parameter sanitization (e.g., during non-save actions or custom actions) allow unsanitized parameters to reach model instantiation, presenting critical mass-assignment and authorization bypass vectors.
Auth Bypass: Flaws in resolving controller contexts, namespaced models, or nested parent models can prevent authorization checks and scope restrictions from executing against the correct targets, leading to silent authorization failures.
SQL Injection: Unsanitized parameter queries using unsafe ID params directly from controller input can lead to SQL injection vulnerabilities in underlying ORMs like ActiveRecord if they are not explicitly cast to simple types.
