Impact
Several HandleRoute endpoints make use of the deprecated ioutil.ReadAll(). ioutil.ReadAll() reads all the data into memory. As such, an attacker who sends a large request to the Argo Events server will be able to crash it and cause denial of service.
Eventsources susceptible to an out-of-memory denial-of-service attack:
- AWS SNS
- Bitbucket
- Bitbucket
- Gitlab
- Slack
- Storagegrid
- Webhook
