CVE-2023-24459Network attack vector

Authenticated server-side request forgery via test connection

Published Jan 24, 2023 · Updated Apr 1, 2025

Server-side request forgery in Jenkins BearyChat Plugin 3.0.2 and earlier allows remote authenticated users to connect to arbitrary URLs. DescriptorImpl.doTestConnection passes the supplied webhook to StandardBearyChatService and calls publish without checking authorization. Overall/Read permission is sufficient, and exploitation causes the Jenkins controller to send a test message to the selected endpoint.
