Jenkins Bitbucket OAuth Plugin 0.17 and earlier does not restrict the redirect URL after login.

This allows attackers to perform phishing attacks by having users go to a Jenkins URL that will forward them to a different site after successful authentication.

Bitbucket OAuth Plugin 0.18 only redirects to relative (Jenkins) URLs.

Fix

Open Redirect
