CVE-2026-73253

A flaw was found in Mongoose. Wildcard certificate matching in its built-in Transport Layer Security TLS stack does not properly restrict matches to a single domain level. An on-path network attacker with a valid wildcard certificate for a parent domain could exploit this flaw to bypass hostname...

CVE-2026-91166

Warpgate is an open source SSH, HTTPS and MySQL bastion host for Linux. From 0.25.0 until 0.27.6, the browser SSH path in warpgate-web-ssh/src/manager.rs handles RCEvent::HostKeyUnknown without the presenting hop identity and instead passes sshoptions.host and sshoptions.port for the final target...

urllib3: urllib3: Traffic interception via HTTPS proxy TLS configuration override

A flaw was found in urllib3. This vulnerability allows a remote attacker on the network to intercept and alter data transmitted through an HTTPS proxy. The issue occurs when target-server Transport Layer Security TLS settings inadvertently overwrite the proxy's TLS configuration, which can disabl...

CVE-2026-91166

Warpgate is an open-source SSH, HTTPS, and MySQL bastion host for Linux. In versions 0.25.0 through 0.27.6 , the browser SSH path mishandles RCEvent::HostKeyUnknown by passing the final target's host and port to KnownHosts::trust instead of the presenting hop's identity. In Prompt and AutoAccept ...

PT-2026-96225

Name of the Vulnerable Software and Affected Versions Warpgate versions 0.25.0 through 0.27.5 Description The browser SSH path in warpgate-web-ssh/src/manager.rs handles RCEvent::HostKeyUnknown without the presenting hop identity. Instead, it passes ssh options.host and ssh options.port for the...

kernel: ip6: vti: Use ip6_tnl.net in vti6_siocdevprivate()

A flaw was found in the Linux kernel's IPv6 Virtual Tunnel Interface VTI module. When a VTI tunnel device is moved to a different network environment, an unprivileged user in a separate user space can manipulate tunnel parameters. This manipulation could allow the user to intercept or redirect...

EUVD-2026-80007

EUVD-2026-80009

On affected platforms running Arista EOS with VRRPv2 IP Authentication Header IP-AH authentication configured, an unauthenticated attacker with access to the layer 2 network segment on which VRRP is running could bypass VRRP authentication and claim the virtual router master role, enabling the...

VulnCheck KEV: CVE-2026-50752

A weakness in the certificate validation logic of the deprecated IKEv1 key exchange may allow an unauthenticated attacker positioned as a man-in-the-middle to bypass certificate validation in VPN site-to-site connections that use certificate-based authentication. Successful exploitation could all...
