EUVD-2026-69788

Mailpit's IsInternalIP deny list function fails to block the Azure WireServer address 168.63.129.16 and the RFC 2765/6145 IPv4-translated IPv6 prefix, allowing server-side request forgery to internal destinations. Attackers can supply hostnames resolving to these addresses in message content to...

CVE-2026-52776

A flaw was found in compliance-trestle. The URLSecurityValidator, intended to prevent Server-Side Request Forgery SSRF, contains a bypass vulnerability. This bypass occurs because the validator does not properly handle IPv4-mapped IPv6 addresses or the unspecified address 0.0.0.0. A remote...

CVE-2026-80350

OneUptime's webhook target check rejects private and loopback addresses given in IPv4 form and a small set of IPv6 forms, but has no case for the IPv4-mapped IPv6 range. The webhook delivery path calls SSRFProtection.validateWebhookTargetIsSafe, and the host-literal screening inside...
