Sources and claim methodology

Upstream source description

The package github.com/runatlantis/atlantis/server/controllers/events before 0.19.7 is vulnerable to Timing Attack in the webhook event validator code, which does not use a constant-time comparison function to validate the webhook secret. It can allow an attacker to recover this secret as an attacker and then forge webhook events.
