String Interpolation's Dark Side: Why eval and Code Injection Pose Critical Risks

String interpolation, a convenient feature in most programming languages, becomes a critical security vulnerability when mishandled through unsafe eval usage, shell injection, or XSS attacks. This article exposes how common coding patterns create exploitable CVEs and why developers must adopt context-specific functions to sanitize user input. Understanding these attack vectors is essential for preventing code injection exploits that regularly compromise production applications.
