# This is a patch to avoid the direct use of `Net::HTTP` in the `webpush` gem and instead rely on `FinalDestination::HTTP`
|
|
# which protects us from DNS rebinding attacks as well as server side forgery requests.
|
|
#
|
|
# This patch is considered temporary until we can decide on a longer term solution. In the meantime, we need to patch
|
|
# the SSRF vulnerability being exposed by this gem.
