CVE-2023-41947Network attack vector

Authenticated external-service access via unchecked HTTP endpoints

Published Sep 6, 2023 · Updated Sep 26, 2024

Missing authorization in Jenkins Frugal Testing Plugin 1.1 and earlier allows remote authenticated users to connect using supplied credentials. Several plugin HTTP endpoints invoke Frugal Testing connection and test-lookup operations without checking the caller's permission. Overall/Read access is sufficient; a valid supplied username also exposes test IDs and names, while no broader impact is reported.
