This vulnerability is like a delivery worker who can access the back office and rummage through all the paperwork without anyone checking their credentials. They could easily grab sensitive files or leave something unwanted behind. This relative path traversal vulnerability allows attackers to manipulate file paths when interacting with the server, enabling access to files outside the intended directory. This happens because the server doesn't validate or restrict file paths properly, letting unauthorized users bypass security measures.
