description

Argo CD releases from 1.5.3 onward may allow concurrent local-account login attempts to exceed the configured failed-login limit. An unauthenticated party that can reach the login API can make additional password guesses when local username/password accounts are enabled.

mitigation

Upgrade github.com/argoproj/argo-cd/v3 to 3.3.15, 3.4.10, 3.5.4, 3.6.0-rc2 or later.

fixed in 3.3.15, 3.4.10, 3.5.4, 3.6.0-rc2
