Regular expression deinal of service in apprise
CVE-2021-39229
Description
Apprise is an open source library which allows you to send a notification to almost all of the most popular notification services available. In affected versions users who use Apprise granting them access to the IFTTT plugin (which just comes out of the box) are subject to a denial of service attack on an inefficient regular expression. The vulnerable regular expression is here. The problem has been patched in release version 0.9.5.1. Users who are unable to upgrade are advised to remove apprise/plugins/NotifyIFTTT.py to eliminate the service.
