It is frequently discussed in research regarding: Local File Inclusion - WSTG - v4.2 | OWASP Foundation It occurs when a web application allows a
In the landscape of web security, remains a critical vulnerability. It occurs when a web application allows a user to input a file path that the server then executes or displays.
