CVE-2022-0086Network attack vector

SSRF via IPv4-mapped IPv6 address bypass

Published Jan 4, 2022 · Updated Aug 2, 2024

SSRF in Transloadit Uppy before 2.3.3 allows remote attackers to make Companion access internal services through IPv4-mapped IPv6 URLs. Companion's request helper checks resolved addresses with incomplete string prefixes, so IPv4-mapped IPv6 forms evade its private-address block. A network-exposed Companion URL import path is required; successful requests can reach otherwise blocked loopback or private HTTP services.
