CVE-2026-494579.1 CRÍ—
———erlang_quic is a pure Erlang QUIC implementation. Prior to version 1.4.4, the QUIC client did not authenticate the server during the TLS 1.3 handshake. The CertificateVerify signature was not checked, the certificate chain was not validated, and the hostname was not compared against the certificate, so `verify` was effectively a no-op on the client. A man-in-the-middle on the network path could present any certificate and impersonate any server, defeating the confidentiality and integrity of the connection. HTTP/3 uses the same client and was equally affected. Handshakes authenticated by a PSK (session resumption) are not affected, because the peer is authenticated by the PSK binder and no certificate is sent. This is fixed in 1.4.4. The client now verifies the CertificateVerify signature, validates the certificate chain against the trust store (`cacerts` option, the operating system store by default), and checks the hostname. Client `verify` now defaults to on; set `verify => false` to accept any certificate (for example a self-signed test server). No known workarounds are available before 1.4.4. `verify => true` had no effect, and inspecting the certificate after connecting does not help because without the signature check the peer is never proven to own the certificate it presents.11hCVE-2026-544817.5 ALT—

——0Improper certificate validation vulnerabilities in Palo Alto Networks GlobalProtect™ app enable an unauthenticated attacker with man-in-the-middle (MitM) access to intercept and modify application communications. VPN tunnel traffic is not impacted.
The GlobalProtect app on iOS, Android, and Chrome OS is not affected.2dCVE-2026-18679—2.1%
——1When 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.2dCVE-2026-18678—0.8%
——0When 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.2dCVE-2026-712909.1 CRÍ5.2%
——2Improper 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.2d
