Details
Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. "Local sync" is an Argo CD feature that allows developers to temporarily override an Application's manifests with locally-defined manifests. Use of the feature should generally be limited to highly-trusted users, since it allows the user to bypass any merge protections in git. An improper validation bug allows users who have `create` privileges but not `override` privileges to sync local manifests on app creation. All other restrictions, including AppProject restrictions are still enforced. The only restriction which is not enforced is that the manifests come from some approved git/Helm/OCI source. The bug was introduced in 1.2.0-rc1 when the local manifest sync feature was added. The bug has been patched in Argo CD versions 2.10.3, 2.9.8, and 2.8.12. Users are advised to upgrade. Users unable to upgrade may mitigate the risk of branch protection bypass by removing `applications, create` RBAC access. The only way to eliminate the issue without removing RBAC access is to upgrade to a patched version.

La \"sincronizaci\u00f3n local\" es una caracter\u00edstica de Argo CD que permite a los desarrolladores anular temporalmente los manifiestos de una aplicaci\u00f3n con manifiestos definidos localmente. El uso de la funci\u00f3n generalmente debe limitarse a usuarios de alta confianza, ya que permite al usuario evitar cualquier protecci\u00f3n de combinaci\u00f3n en git. Un error de validaci\u00f3n inadecuado permite a los usuarios que tienen privilegios de \"crear\" pero no privilegios de \"anular\" sincronizar manifiestos locales al crear la aplicaci\u00f3n. Todas las dem\u00e1s restricciones, incluidas las de AppProject, a\u00fan se aplican. La \u00fanica restricci\u00f3n que no se aplica es que los manifiestos provengan de alguna fuente aprobada de git/Helm/OCI. El error se introdujo en 1.2.0-rc1 cuando se agreg\u00f3 la funci\u00f3n de sincronizaci\u00f3n del manifiesto local. El error se ha solucionado en las versiones 2.10.3, 2.9.8 y 2.8.12 de Argo CD. Se recomienda a los usuarios que actualicen. Los usuarios que no puedan actualizar pueden mitigar el riesgo de eludir la protecci\u00f3n de sucursal eliminando el acceso RBAC \"aplicaciones, creaci\u00f3n\". La \u00fanica forma de eliminar el problema sin eliminar el acceso a RBAC es actualizar a una versi\u00f3n parcheada."
