Description: Log Injection occurs when untrusted user input is directly written to log files without proper sanitization. This can allow attackers to manipulate log entries, potentially leading to security issues like log forging or cross-site scripting. To prevent this, always sanitize user input before logging by removing or encoding newline characters, using string encoding functions, and leveraging built-in sanitization features of logging libraries when available.

Description: Path traversal vulnerability detected. User-controlled input in filesystem operations allows attackers to access files outside intended directories. This can lead to unauthorized access to sensitive system files and exposure of confidential data. To remediate: Use path.basename() to strip directory components, explicitly check for path traversal sequences "..", and validate final paths remain within authorized directories.

Description: Server-Side Request Forgery (SSRF) vulnerability detected.
Untrusted user input is being used in a network request without proper validation.
This can allow attackers to craft requests to internal systems, access metadata services,
or perform internal port scans. To fix this issue, strictly validate and sanitize the input URL
using a library like node:url for parsing, enforce an allowlist of trusted domains,
and block access to private IP ranges (e.g., 127.0.0.1, 169.254.169.254).
