CVE-2026-70438Network attack vector

Credential ID disclosure via unchecked HTTP endpoints

Published Aug 5, 2026 · Updated Aug 5, 2026

Missing authorization in Jenkins Parameterized Remote Trigger Plugin 3.2.2 and earlier allows remote authenticated users to enumerate credential IDs. The affected HTTP endpoints return identifiers for credentials stored in Jenkins without checking any permission beyond Overall/Read; Jenkins has not disclosed the endpoint names. Overall/Read access is required, and the identifiers do not reveal secret values but can support credential capture through a separate flaw.
