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. An attacker with Overall/Read permission could make Jenkins connect to a URL they specify using credential IDs they specify, which can capture credentials stored in Jenkins. The endpoint also does not require POST requests, so it is open to cross-site request forgery. No fix is listed.
