CVE-2026-44345: Ssrf Toctou Dns Rebinding
A URL validation check is performed before an HTTP request, but the original URL string is passed to the network client. If the validation performs an IP address check via DNS resolution, this pattern is susceptible to Time-of-Check to Time-of-Use (TOCTOU) DNS Rebinding attacks. To fix this, resolve the IP securely and pass the IP directly to the HTTP client
