Description Marian Rehak 2021-09-30 13:26:03 UTC 
Users who use Apprise granting them access to the IFTTT plugin are subject to a denial of service attack on an inefficient regular expression. Users who are unable to upgrade are advised to remove `apprise/plugins/NotifyIFTTT.py` to eliminate the service.
