CVE-2026-50240

Full vulnerability record from the local CVENow database.
Description

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.
