Short explanation
An authorization flaw in OpenShift Pipelines-as-Code allows attackers to perform namespace-scoped privilege escalation via an auto-provisioned service account.
This vulnerability enables low-privileged users to read secrets, modify resources, and perform supply chain injection within CI/CD namespaces.
What should be done?
- Follow the vendor advisory
Chain of evidence and sources
OpenShift Pipelines-as-Code, Repository özel kaynağını oluşturan kullanıcının PipelineRuns oluşturma iznini doğrulamamaktadır.
Yetkilendirme eksikliği, ad alanı düzeyinde ayrıcalık yükseltmeye ve kaynak manipülasyonuna yol açar.
Show the technical text from the sources
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.
