Details

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.

GHSA-QHMP-H54X-38QR

Vulnerability from github – Published: 2021-09-20 20:57 – Updated: 2024-09-12 20:54

Summary

Apprise vulnerable to regex injection with IFTTT Plugin

Details

Impact

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

Patches

Update to Apprise v0.9.5.1 bash # 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.
