AI Summary

Fixes for header injection vulnerabilities and enforcement of deprecated path variable syntax.

Key Highlights

Fixed backslash and double quote escaping in `Content-Disposition` filenames to prevent header injection.
`vpath!` macro now enforces new `{var}` syntax, rejecting old `:var` or `*var` formats.
Fixed specific error message when multipart body limit is exceeded.

Breaking Changes

Deprecated path variables in `vpath!` macro (e.g., `:var`, `*var`) are no longer allowed.

Full Release Notes

- **fixed:** Escape backslashes and double quotes in `Content-Disposition` filenames to prevent header parameter injection in `Attachment` and `FileStream` ([#3664])
- `vpath!` macro now stops the compilation if your path is using deprecated path variables in the old `107` format, such as `:var` and `*var`. the only allowed way now is `{var}`. ([#3618])
- **fixed:** Return specific error message when multipart body limit is exceeded ([#3611])
