Description
Added a new Application-Level Path Traversal section to Directory Traversal, covering common patterns where user-controlled input (session IDs, usernames, filenames) is used in filesystem operations without validation.
What's Added
sendFileMotivation
The existing Directory Traversal section focuses on web/HTTP path traversal. This addition covers application-level path traversal — a common vulnerability in APIs and backend services where user input flows directly into filesystem operations like
Path / user_input,shutil.rmtree(),os.path.join(), orres.sendFile().The Python patterns are based on real fixes from production codebases.
