Detailed vulnerability description
The vulnerability allows a remote attacker to send requests to loopback, private network, or link-local metadata endpoints.
The vulnerability exists due to insufficient SSRF protection in the SSRF guard in src/infra/net/ssrf.ts when processing full-form IPv4-mapped IPv6 literals. A remote attacker can supply a crafted IPv6 address to send requests to loopback, private network, or link-local metadata endpoints.
Full-form IPv4-mapped IPv6 literals such as 0:0:0:0:0:ffff:7f00:1 can bypass IP classification checks.
