Medium (4.2). EPSS 0.1% chance of exploitation in the next 30 days.

The OAuth authorization endpoint in Jenkins Bitbucket Server Integration Plugin 6.0.1 and earlier reads the `oauth_callback` URL from the submitted form rather than from the server-side stored request token, allowing attackers to hijack the OAuth flow and obtain an access token on behalf of the victim.
