CVE-2026-55787

Flyto2 Core is an execution kernel for automation and AI-agent workflows. Prior to 2.26.3, validateurlssrf and isprivateip in src/core/utils.py compare resolved addresses only against native private IPv4 and IPv6 ranges and do not unwrap IPv4-mapped, IPv4-compatible, 6to4, or NAT64 transition...

In versions 1.56.0 through 1.101.0, 2.0.0b1, and 2.0.0b2, the cloud-metadata blocklist could be bypassed by encoding the metadata IP in an IPv6 transition form that the previous fix, CVE-2026-46678...

Crawl4AI: SSRF filter bypass in Docker server via IPv6 transition forms (NAT64 / 6to4 / unspecified / v4-mapped)

Summary The Docker API server's SSRF protection validatewebhookurl / validateurldestination in deploy/docker/utils.py used an explicit IPv4/IPv6 CIDR blocklist that missed several address families. An attacker could reach internal services and cloud metadata endpoints e.g. 169.254.169.254 despite...
