CVE-2026-50752 (GCVE-0-2026-50752)

Vulnerability from cvelistv5 – Published: 2026-06-08 11:00 – Updated: 2026-06-10 13:36

Title

Certificate Validation Bypass in VPN Site-to-Site Connections Using IKEv1

Summary

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 allow interception or modification of traffic traversing the VPN tunnel.

Severity

7.4 (High)
