{"cve":"CVE-2025-3445","nvd":{"published":"2025-04-13T22:15:12.870","modified":"2026-06-17T09:19:58.147","status":"Deferred","description":"A Path Traversal \"Zip Slip\" vulnerability has been identified in mholt/archiver in Go. This vulnerability allows using a crafted ZIP file containing path traversal symlinks to create or overwrite files with the user's privileges or application utilizing the library.\n\nWhen using the archiver.Unarchive functionality with ZIP files, like this: archiver.Unarchive(zipFile, outputDir),  A crafted ZIP file can be extracted in such a way that it writes files to the affected system with the same privileges as the application executing this vulnerable functionality. Consequently, sensitive files may be overwritten, potentially leading to privilege escalation, code execution, and other severe outcomes in some cases.\n\nIt's worth noting that a similar vulnerability was found in TAR files (CVE-2024-0406). Although a fix was implemented, it hasn't been officially released, and the affected project has since been deprecated. The successor to mholt/archiver is a new project called mholt/archives, and its initial release (v0.1.0) removes the Unarchive() functionality.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:H/A:L","score":8.1},"cwes":["CWE-22"],"references":["https://github.com/mholt/archiver/"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:00:57.946988208+00:00"},"epss":{"cve":"CVE-2025-3445","score":0.00508,"percentile":0.43431,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-7vpp-9cxj-q8gv","url":"https://osv.dev/vulnerability/GHSA-7vpp-9cxj-q8gv","summary":"mholt/archiver Vulnerable to Path Traversal via Crafted ZIP File","modified":"2026-09-10T03:50:23.577691904Z","packages":[{"ecosystem":"Go","name":"github.com/mholt/archiver","purl":"pkg:golang/github.com/mholt/archiver","ranges":["<=3.5.1"],"fixed":[]},{"ecosystem":"Go","name":"github.com/mholt/archiver/v3","purl":"pkg:golang/github.com/mholt/archiver/v3","ranges":["<=3.5.1"],"fixed":[]}]},{"id":"GO-2025-3605","url":"https://osv.dev/vulnerability/GO-2025-3605","summary":"Vulnerable to Path Traversal via Crafted ZIP File in github.com/mholt/archiver","modified":"2026-02-04T04:25:40.379939Z","packages":[{"ecosystem":"Go","name":"github.com/mholt/archiver","purl":"pkg:golang/github.com/mholt/archiver","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/mholt/archiver/v3","purl":"pkg:golang/github.com/mholt/archiver/v3","ranges":["all versions"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
