SQL injection has been studied and discussed for more than 20 years, yet more than 20% of organizations are still vulnerable when first assessed, and the technique continues to account for a meaningful share of modern vulnerabilities.

Cross-site scripting (XSS) is another long-standing example. It allows attackers to inject malicious scripts into web applications, enabling data theft, session hijacking, and unauthorized actions on behalf of legitimate users.

The technique has persisted since the late 1990s and continues to appear in modern applications, including those built on frameworks that claim to mitigate it by default.
