Detects incoming HTTP requests that use URL-encoding (e.g., %2e%2e, %2f) to obfuscate path traversal sequences targeting sensitive operating system or container application files, such as /proc/self/environ or /etc/passwd. This technique is often used to bypass security filters or URL validation mechanisms in web applications.
