description
zip2 versions through 9.0.4 can interpret ZIP entry names differently during inspection and streamed extraction. An attacker able to provide an archive may bypass central-directory-based checks and cause extracted content to be written to another path, potentially replacing files used by a downstream service.
mitigation
Upgrade zip2 to version 9.0.5 or later. Until upgraded, do not stream-extract untrusted ZIP archives based solely on central-directory validation.
fixed in 9.0.5
outcome
Contextual, not validated: no deterministic check could cover this one, and no technique passed our review.
