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.\n\nFor further details see: https://github.com/zip-rs/zip2/security/advisories/GHSA-4v9h-p7m9-rh26\n\n## Affected packages\n\n- `zip >= 0.0.0-0, < 9.0.0`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `zip 9.0.0`","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
