Apprise vulnerable to regex injection with IFTTT Plugin

Impact

Anyone publicly hosting the Apprise library and granting them access to the IFTTT notification service.

Patches

Update to Apprise v0.9.5.1

# Install Apprise v0.9.5.1 from PyPI
pip install apprise==0.9.5.1

The patch to the problem was performed here.

Workarounds

Alternatively, if upgrading is not an option, you can safely remove the following file:

• apprise/plugins/NotifyIFTTT.py

The above will eliminate the ability to use IFTTT, but everything else will work smoothly.
