CVE-2026-92138
Published:September 16, 2026
Updated:September 22, 2026
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.
