| Package | Affected versions | Patched versions |
|---|---|---|
| hastymail | ≤ 1.0.1≤ 1.1 |
Hastymail 1.0.1 and earlier (stable) and 1.1 and earlier (development) does not send the "attachment" parameter in the Content-Disposition field for attachments, which causes the attachment to be rendered inline by Internet Explorer when the victim clicks the download link, which facilitates cross-site scripting (XSS) and possibly other attacks.
