Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThis is a cross-site request forgery (CSRF) vulnerability in the Jenkins Health Advisor by CloudBees Plugin version 3.0 and earlier. The flaw allows an attacker to craft malicious requests that, when triggered by an authenticated user, will cause the Jenkins server to send emails with predetermined content to any recipient address specified by the attacker. The vulnerability exploits the lack of anti-CSRF tokens in the email-sending functionality.
