CVE-2026-105689

Penpot is an open-source design and prototyping platform. Prior to 2.18.0, app.util.ssrf/blocked-address? relies on Java InetAddress predicates that do not classify NAT64, 6to4, or Teredo addresses and applies additional CIDR checks only to IPv4 values. Exploitation requires routing through a NAT...

CVE-2026-85738 TREK: SSRF Guard Bypass via IPv6 Transition Addresses (NAT64/6to4)

TREK is a collaborative travel planner. Prior to 3.4.0, the checkSsrf logic in server/src/utils/ssrfGuard.ts does not recognize NAT64, 6to4, or Teredo IPv6 transition addresses that encode an IPv4 destination. An authenticated user who controls a DNS record can supply a URL whose AAAA result is a...

CVE-2026-85738

The collaborative travel planner TREK (prior to version 3.4.0 ) is vulnerable to a Server-Side Request Forgery (SSRF) due to a flaw in the checkSsrf logic located in server/src/utils/ssrfGuard.ts. The application fails to recognize NAT64, 6to4, or Teredo IPv6 transition addresses that encode an I...

CVE-2026-93597: Server-Side Request Forgery (SSRF)

ArcadeDB versions before 26.9.1 fail to validate IPv6 transition addresses in the SSRF guard used by IMPORT DATABASE and server commands. Authenticated attackers can supply URLs resolving to NAT64, 6to4, or Teredo addresses embedding RFC 1918 or loopback IPv4 payloads to reach internal services a...

CVE-2026-88896

EspoCRM before 10.0.4 is vulnerable to Server-Side Request Forgery (SSRF) via an IPv6 transition address bypass in HostCheck::ipAddressIsNotInternal(). The function strips ::ffff: (IPv4-mapped IPv6) prefixes but fails to recognize IPv6 transition addresses that embed private IPv4 addresses—NAT64 ...
