HestiaCP IP Spoofing Vulnerability (CVE-2026-43634)

HestiaCP versions 1.2.0 through 1.9.4 are vulnerable to IP spoofing (CVE-2026-43634), allowing unauthenticated remote attackers to bypass authentication security controls by manipulating the CF-Connecting-IP HTTP header to circumvent fail2ban, bypass IP allowlists, and poison authentication logs.

zrok ProxyShare SSRF Vulnerability (CVE-2026-45568)

The zrok Python SDK `ProxyShare` is vulnerable to server-side request forgery (SSRF) via CVE-2026-45568. When a user sends a request with an absolute URL in the path, the Flask handler passes that path to `urllib.parse.urljoin`, which replaces the configured target host with the user-supplied host, causing the proxy to send the request to an attacker-chosen URL.
