Impact
Messages sent using this script are vulnerable to abuse, as the script allows anybody to specify arbitrary email recipients and include user-provided content in confirmation emails.

Patches
Patched in version 1.0.0 by removing user-provided content from confirmation emails. All pre-release versions (alpha and beta) are vulnerable to this issue and should not be used.
Workarounds
There are no workarounds for this issue. Users must upgrade to version 1.0.0 to mitigate the vulnerability.
