Not enough EPSS history yet.
When kuma-dp is started against an HTTPS control plane and the operator did not pass a CA certificate, the data plane connects with TLS peer verification disabled, and the dataplane authentication token is sent over that unverified connection. An on-path actor can intercept the dataplane authentication token and impersonate the control plane to the data plane, injecting a forged bootstrap configuration and taking over the proxy.

CVE-2026-18678——
———When an operator adds an HTTPS control plane profile to kumactl without providing a CA certificate, kumactl disables TLS verification and sends API tokens over the unverified connection.
An attacker on the network path between the operator and the control plane can intercept user or admin API tokens and then act against the control plane as that user.7hCVE-2026-712909.1 CRI—
——0Improper TLS hostname verification vulnerability in Apache HttpComponents Client 5.4 or newer. HostnameVerificationPolicy#BUILTIN setting has no effect when used with the async version of HttpClient. An attacker that can intercept and modify traffic between the client and
the server can impersonate the server by presenting a valid certificate
for a different domain.
Please note the classic version of HttpClient is not affected by this vulnerability.
Affected users are recommended to upgrade to at least version 5.6.4, which fixes the issue.5hCVE-2026-661548.3 HIG—
——0An insufficient certificate validation in a privileged communication workflow, was identified in a GMS application 9.5.1 (Build 9510.1044) and earlier versions which, under a successful MitM attack and controlled network conditions, could permit unauthorized changes.11hCVE-2026-484375.5 MED—
——0CAI Content Credentials is affected by an Improper Certificate Validation vulnerability that could result in a Security feature bypass. An attacker could leverage this vulnerability to bypass security measures and gain unauthorized write access. Exploitation of this issue requires user interaction in that a victim must visit a maliciously crafted URL or interact with a compromised web page.5hCVE-2026-11814——
——0A command injection vulnerability in the listed NETGEAR models allows a network-adjacent attacker with the ability to intercept and modify local network traffic (attacker-in-the-middle) to compromise the confidentiality and integrity of the affected device. This issue is limited to certain region-specific SKUs.11hCVE-2026-181298.1 HIG—
——0Cleartext transmission of sensitive information in the Core of Ivanti Endpoint Manager before version 2024 SU7 allows a remote unauthenticated attacker in a MITM position to leak credentials for external SQL connections.21h
