Uses of deprecated API can be used to cause DoS in user-facing endpoints

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

Patches

A patch for this vulnerability has been released in the following Argo Events version:
