CVE-2026-50240

pipelines-as-code · Vulnerability

CVSS 3.1 8.8 HIGHCheck source for fixed versionsKEV status unknown
Original advisory

cve-program · CVE-2026-50240

Published

A flaw was found in OpenShift Pipelines-as-Code (PAC). PAC does not verify whether the creator of a Repository custom resource has permission to create PipelineRuns. A namespace user with only Repository and Secret create/delete permissions can cause PAC to execute attacker-controlled PipelineRuns as the auto-provisioned pipeline ServiceAccount, which carries ClusterRole/edit by default. This results in namespace-scoped privilege escalation, enabling Secret read, resource creation/modification/deletion, and potential supply chain injection in CI/CD namespaces.
