This vulnerability occurs when a program calls a function but supplies the arguments in the wrong order, which can cause unexpected behavior or security flaws.
This error happens when the sequence of values passed to a function doesn't match the order its parameters expect. For example, swapping a username and password argument could grant unintended access. While modern compilers for strongly-typed languages often catch these mistakes, they slip through more easily in languages with flexible function signatures. It's particularly common in functions that accept variable arguments, like C's `printf` format strings, or in dynamically-typed environments where type checking is minimal. Developers should rely on named parameters when available, use static analysis tools, and maintain clear documentation for function interfaces to prevent these subtle but dangerous bugs.
