zip: creates symbolic links whose attacker-controlled targets are outside the destination directory
Published Oct 9, 2026 · corrected/updated Oct 16, 2026 · evidence confidence medium
In 9.0.0-pre2, creates a symbolic link from an archive entry after validating only the output entry path. The link target bytes are passed directly to the platform symlink API, so a malicious archive can create an entry inside the destination that resolves to an attacker-chosen path outside it. This behavior was verified on macOS and Linux. On either platform, a subsequent application read or write through that extracted entry accesses the external target with the extracting process's permissions.

Grounded briefings
Catalog interpretations for three audiences. Each brief cites ingested metadata and the original advisories below. They are not independent research and they do not invent exploit steps.
Executive
RUSTSEC-2026-0368 is a unknown public vulnerability record for this product. It is not currently listed in the CISA Known Exploited catalog. Check the linked vendor or CERT advisories for patch status. This summary is a catalog interpretation of the ingested metadata and cites the original advisories below.
System administrator
Identify whether this product is in your estate, then compare installed versions with the affected ranges. Affected packages or ranges on record: zip (0.0.0-0 → 9.0.0). Check the linked vendor or CERT advisories for patch status. Prefer the vendor or distribution advisory linked in Sources before changing production systems. This is a catalog interpretation, not a runbook.
Security analyst
Signals on file: no CVSS/EPSS yet. It is not currently listed in the CISA Known Exploited catalog. Sources contributing to this record: github, osv. Public exploit references, when present, are outbound links only and are not proof of active exploitation. This is a catalog interpretation of stored metadata.
Exploitation and remediation
