CVE-2022-28133
Published: 29 March 2022
Summary
CVE-2022-28133 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Jenkins Bitbucket Server Integration. Its CVSS base score is 5.4 (Medium).
Operationally, ranked at the 42.7th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
Deeper analysis
Jenkins Bitbucket Server Integration Plugin 3.1.0 and earlier contains a stored cross-site scripting vulnerability because the plugin does not restrict URL schemes for OAuth consumer callback URLs. The affected component is the Jenkins plugin that integrates with Bitbucket Server for source-code management workflows.
Attackers who can create Bitbucket Server consumers are able to supply a malicious callback URL that is stored and later rendered in the Jenkins interface. Successful exploitation produces reflected script execution with limited impact on confidentiality and integrity while requiring user interaction from a victim administrator or user.
The Jenkins security advisory published on 2022-03-29 and the corresponding oss-security mailing list posting describe the issue under SECURITY-2639 and recommend upgrading the plugin to a fixed release that enforces an allow-list of permitted URL schemes.
EPSS for the CVE rose sharply from a low baseline to a peak of 0.3160 on 2025-12-11 before receding, indicating measurable post-disclosure exploitation interest that warrants renewed monitoring.
