GHSA-qhmp-h54x-38qr
Apprise vulnerable to regex injection with IFTTT Plugin
Packages
Details
As written in the advisory (Markdown source, shown as plain text).
### 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](https://github.com/caronc/apprise/pull/436/files).
### 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.
