In go-ipfs before version 0.8.0-rc1, it is possible for path traversal to occur with DAGs containing relative paths during retrieval. This can cause files to be overwritten, or written to incorrect output directories. The issue can only occur when a get is done on an affected DAG. This is fixed in version 0.8.0-rc1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","score":8.1},"cwes":["CWE-22"],"references":["https://github.com/ipfs/go-ipfs/commit/b7ddba7fe47dee5b1760b8ffe897908417e577b2","https://github.com/ipfs/go-ipfs/security/advisories/GHSA-27pv-q55r-222g","https://github.com/whyrusleeping/tar-utils/commit/20a61371de5b51380bbdb0c7935b30b0625ac227","https://github.com/ipfs/go-ipfs/commit/b7ddba7fe47dee5b1760b8ffe897908417e577b2","https://github.com/ipfs/go-ipfs/security/advisories/GHSA-27pv-q55r-222g"],"products":["protocol:go-ipfs"],"source":"nvd","synced_at":"2026-10-19T21:15:50.279857260+00:00"},"epss":{"cve":"CVE-2020-26279","score":0.01699,"percentile":0.77196,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-27pv-q55r-222g","url":"https://osv.dev/vulnerability/GHSA-27pv-q55r-222g","summary":"Path traversal in github.com/ipfs/go-ipfs","modified":"2026-09-10T03:49:14.888691728Z","packages":[{"ecosystem":"Go","name":"github.com/ipfs/go-ipfs","purl":"pkg:golang/github.com/ipfs/go-ipfs","ranges":["<0.8.0"],"fixed":["0.8.0"]}]},{"id":"GO-2022-0779","url":"https://osv.dev/vulnerability/GO-2022-0779","summary":"Path traversal in github.com/ipfs/go-ipfs","modified":"2026-03-03T04:50:53.152414Z","packages":[{"ecosystem":"Go","name":"github.com/ipfs/go-ipfs","purl":"pkg:golang/github.com/ipfs/go-ipfs","ranges":["<0.8.0"],"fixed":["0.8.0"]}]}],"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).
