Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Prototype Pollution: Deep property resolution via _fnSetObjectDataFn can be abused to pollute the prototype chain, allowing remote attackers to inject arbitrary properties. Earlier fixes blocklisting '__proto__' had to be revised to additionally block 'constructor' properties to prevent bypasses.

SQL Injection: Server-side examples used insecure parameters in database queries. Standard string escaping is insufficient for SQL clauses like LIMIT and ORDER BY; strict integer casting and keyword allowlists are required to secure these parameters.

Reflected XSS: Directly reflecting user-supplied parameters like callback names in JSONP responses or scripts in template files allows execution of arbitrary JavaScript in the user's browser context.
