Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Jenkins Publish to Bitbucket Plugin version 0.4 and earlier has an HTTP endpoint that lacks a permission check and does not require POST requests. An attacker with Overall/Read permission, who also obtains valid credentials IDs by other means, can make Jenkins connect to an attacker-specified URL and capture credentials stored in Jenkins; the missing POST requirement also makes it open to cross-site request forgery. No fix is listed, and the source gives no workaround.
