CVE-2026-52724 kuma-dp connects to control plane without verifying TLS certificate when no CA is configured

Kuma is a modern Envoy-based service mesh that can run on every cloud across both Kubernetes and VMs. Prior to 2.7.26, 2.9.16, 2.11.14, 2.12.11, and 2.13.7, Universal mode kuma-dp connections to an HTTPS control plane disable TLS peer verification when --ca-cert-file is not supplied and...

CVE-2026-52724: Improper Certificate Validation

Kuma is a modern Envoy-based service mesh that can run on every cloud across both Kubernetes and VMs. Prior to 2.7.26, 2.9.16, 2.11.14, 2.12.11, and 2.13.7, Universal mode kuma-dp connections to an HTTPS control plane disable TLS peer verification when --ca-cert-file is not supplied and...

rsync: rsync: TLS Certificate Validation Bypass allows interception of encrypted sessions

A flaw was found in the rsync-ssl wrapper script's TLS certificate validation. An on-path attacker can present self-signed or invalid certificates to intercept, decrypt, or tamper with encrypted sessions. Because rsync fails to validate the certificate against a trusted CA or verify hostname...

Snowflake Connector for Python improperly verifies TLS hostnames

Improper TLS hostname verification in Snowflake Connector for Python versions prior to 4.7.1 and 3.18.1 may have allowed a network-positioned attacker to bypass certificate hostname validation on HTTPS connections made by the connector. An attacker with on-path network access could exploit this b...

SUSE CVE-2026-79779

rclone versions before v1.75.0 fail to reject transport downgrades in redirect handling, allowing Basic authorization and Cookie headers to be replayed over plaintext HTTP after same-host HTTPS-to-HTTP redirects. An on-path attacker observing the plaintext hop can capture and reuse credentials to...

CVE-2026-79779

A flaw was found in rclone. The application fails to reject transport downgrades during redirect handling, which allows Basic authorization and Cookie headers to be replayed over plaintext HTTP following HTTPS-to-HTTP redirects on the same host. An on-path attacker can observe this plaintext...

Devolutions Remote Desktop Manager 2026.1.x < 2026.1.25.0 / 2026.2.x < 2026.2.18.0 Insufficient Data Authenticity Verification (CVE-2026-78417)

The version of Devolutions Remote Desktop Manager installed on the remote host is 2026.1.x prior to 2026.1.25.0 or 2026.2.x prior to 2026.2.18.0. It is, therefore, affected by a vulnerability: - Insufficient verification of data authenticity in the IronVNC client allows an on-path attacker to...

Linux Distros Unpatched Vulnerability : CVE-2026-79779
