Prior to 0.0.36, a malicious user with permission to edit the local-path-config ConfigMap in the local-path-storage namespace can manipulate the helperPod.yaml template used by rancher/local-path-provisioner. The helperPod.yaml template is loaded by the provisioner and used to create HelperPods during PVC provisioning and cleanup operations. However, the template is not sufficiently validated before use. Security-sensitive fields such as securityContext.privileged, hostPath volumes, and Linux capabilities can be injected into the template. When a PVC operation triggers HelperPod creation, the provisioner creates the HelperPod using the attacker-controlled template. This can result in a privileged pod running on the target node with the host root filesystem mounted. This may allow the attacker to access sensitive host files, read ServiceAccount tokens from other pods on the same node, access other tenants' local-path volume data, or modify files on the host node. This vulnerability is fixed in 0.0.36."},{"lang":"es","value":"Local Path Provisioner proporciona una forma para que los usuarios de Kubernetes utilicen el almacenamiento local en cada nodo. Antes de la versión 0.0.36, un usuario malintencionado con permiso para editar el ConfigMap local-path-config en el espacio de nombres local-path-storage puede manipular la plantilla helperPod.yaml utilizada por rancher/local-path-provisioner. La plantilla helperPod.yaml es cargada por el provisioner y utilizada para crear HelperPods durante las operaciones de aprovisionamiento y limpieza de PVC. Sin embargo, la plantilla no es suficientemente validada antes de su uso. Campos sensibles a la seguridad como securityContext.privileged, volúmenes hostPath y capacidades de Linux pueden ser inyectados en la plantilla. Cuando una operación de PVC desencadena la creación de un HelperPod, el provisioner crea el HelperPod utilizando la plantilla controlada por el atacante. Esto puede resultar en un pod privilegiado ejecutándose en el nodo objetivo con el sistema de archivos raíz del host montado. Esto puede permitir al atacante acceder a archivos sensibles del host, leer tokens de ServiceAccount de otros pods en el mismo nodo, acceder a datos de volumen local-path de otros inquilinos o modificar archivos en el nodo host. Esta vulnerabilidad está corregida en la versión 0.0.36."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"rancher","product":"local-path-provisioner","versions":[{"version":"< 0.0.36","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:N","baseScore":8.7,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"HIGH","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"NONE"},"exploitabilityScore":2.3,"impactScore":5.8}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-05-30T01:59:44.054722Z","id":"CVE-2026-44543","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-269"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:suse:local_path_provisioner:*:*:*:*:*:kubernetes:*:*","versionEndExcluding":"0.0.36","matchCriteriaId":"748A67A9-AB0D-4258-AC98-B369A1BBD60A"}]}]}],"references":[{"url":"https://github.com/rancher/local-path-provisioner/security/advisories/GHSA-7fxv-8wr2-mfc4","source":"security-advisories@github.com","tags":["Mitigation","Vendor Advisory"]}]}
