vpn authentication bypass

The vpn authentication bypass tag covers vulnerabilities and exploits that allow attackers to bypass authentication on VPN gateways, particularly in enterprise environments. Recent content highlights CISA adding CVE-2026-0257, a PAN-OS GlobalProtect authentication bypass vulnerability under active exploitation, to its Known Exploited Vulnerabilities catalog. This underscores the ongoing risk to remote access infrastructure, especially for Windows-heavy organizations that rely on VPNs for network entry. Discussions focus on the broader implications of such bypasses, emphasizing that VPN authentication bypass is not just a vendor-specific issue but a fundamental trust problem in remote access security. The tag includes threat intelligence, patch deadlines, and mitigation strategies for IT administrators.
