If an attacker can pollute Object.prototype.proxy, affected requests can be routed through an attacker-controlled proxy. For plaintext HTTP requests, the proxy can observe Authorization headers, Basic auth from config.auth, method, absolute URL, Host, and request body, and can return its own response. This does not establish browser impact or HTTPS header/body disclosure under normal TLS validation. Affected versions are >=0.31.1 (fixed in 0.33.0) and >=1.15.2 (fixed in 1.18.0). ## Remediation Refer to the linked advisories for vendor-supplied fixes and affected version ranges. ## Vendor advisories - **RHSA-2026:60387** · Red Hat · fixed in: Red Hat Advanced Cluster Management for Kubernetes 2.11 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60387) - **RHSA-2026:60390** · Red Hat · fixed in: Red Hat Advanced Cluster Management for Kubernetes 2.13 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60390) - **RHSA-2026:60388** · Red Hat · fixed in: Red Hat Advanced Cluster Management for Kubernetes 2.14 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60388) - **RHSA-2026:61691** · Red Hat · fixed in: Red Hat Container Native Virtualization 4.12 · released 2026-08-31 · [advisory](https://access.redhat.com/errata/RHSA-2026:61691) - **RHSA-2026:47619** · Red Hat · fixed in: Red Hat Hardened Images · released 2026-07-28 · [advisory](https://access.redhat.com/errata/RHSA-2026:47619) - **RHSA-2026:48241** · Red Hat · fixed in: Red Hat Hardened Images · released 2026-07-29 · [advisory](https://access.redhat.com/errata/RHSA-2026:48241) - **RHSA-2026:48758** · Red Hat · fixed in: Red Hat Hardened Images · released 2026-07-30 · [advisory](https://access.redhat.com/errata/RHSA-2026:48758) - **RHSA-2026:59548** · Red Hat · fixed in: Red Hat OpenShift Service Mesh 3.0 · released 2026-08-25 · [advisory](https://access.redhat.com/errata/RHSA-2026:59548) - **RHSA-2026:59561** · Red Hat · fixed in: Red Hat OpenShift Service Mesh 3.1 · released 2026-08-25 · [advisory](https://access.redhat.com/errata/RHSA-2026:59561) - **RHSA-2026:59554** · Red Hat · fixed in: Red Hat OpenShift Service Mesh 3.2 · released 2026-08-25 · [advisory](https://access.redhat.com/errata/RHSA-2026:59554) - **RHSA-2026:59566** · Red Hat · fixed in: Red Hat OpenShift Service Mesh 3.3 · released 2026-08-25 · [advisory](https://access.redhat.com/errata/RHSA-2026:59566) - **Red Hat VEX** · Important · affected: Migration Toolkit for Applications 8, Multicluster Engine for Kubernetes, OpenShift Pipelines, Red Hat Advanced Cluster Security 4, Red Hat Ansible Automation Platform 2, Red Hat build of Apicurio Registry 3, … · no fix planned: Red Hat Ansible Automation Platform 2, Migration Toolkit for Applications 8, Multicluster Engine for Kubernetes, OpenShift Pipelines, … · updated 2026-09-21 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-67320.json) - **RHSA-2026:65118** · Red Hat · fixed in: Red Hat Ansible Automation Platform 2.1 · released 2026-09-08 · [advisory](https://access.redhat.com/errata/RHSA-2026:65118) - **RHSA-2026:65126** · Red Hat · fixed in: Red Hat OpenShift AI 2.25 · released 2026-09-08 · [advisory](https://access.redhat.com/errata/RHSA-2026:65126) - **RHSA-2026:68681** · Red Hat · fixed in: Red Hat Migration Toolkit 1.8 · released 2026-09-17 · [advisory](https://access.redhat.com/errata/RHSA-2026:68681) - **RHSA-2026:68754** · Red Hat · fixed in: Red Hat OpenShift Dev Spaces 3.30 · released 2026-09-17 · [advisory](https://access.redhat.com/errata/RHSA-2026:68754)
