From version 1.4.0 to before version 2.3.3, a crafted wheel can contain ../ paths that Poetry writes to disk without containment checks, allowing arbitrary file write with the privileges of the Poetry process. It is reachable from untrusted package artifacts during normal install flows. (Normally, installing a malicious wheel is not sufficient for execution of malicious code. Malicious code will only be executed after installation if the malicious package is imported or invoked by the user.). This issue has been patched in version 2.3.3.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","score":7.1},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N","score":6.5},"cwes":["CWE-22"],"references":["http://github.com/python-poetry/poetry/commit/ed59537ac3709cfbdbf95d957de801c13872991a","https://github.com/python-poetry/poetry/pull/10792","https://github.com/python-poetry/poetry/releases/tag/2.3.3","https://github.com/python-poetry/poetry/security/advisories/GHSA-2599-h6xx-hpxp","https://github.com/python-poetry/poetry/security/advisories/GHSA-2599-h6xx-hpxp"],"products":["python-poetry:poetry"],"source":"nvd","synced_at":"2026-10-19T22:28:18.033120106+00:00"},"epss":{"cve":"CVE-2026-34591","score":0.00486,"percentile":0.41889,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-2599-h6xx-hpxp","url":"https://osv.dev/vulnerability/GHSA-2599-h6xx-hpxp","summary":"Poetry Has Wheel Path Traversal Which Can Lead to Arbitrary File Write","modified":"2026-09-10T03:50:42.075152286Z","packages":[{"ecosystem":"PyPI","name":"poetry","purl":"pkg:pypi/poetry","ranges":[">=1.4.0 <2.3.3"],"fixed":["2.3.3"]}]},{"id":"PYSEC-2026-2260","url":"https://osv.dev/vulnerability/PYSEC-2026-2260","summary":"","modified":"2026-07-13T07:15:36.423234295Z","packages":[{"ecosystem":"PyPI","name":"poetry","purl":"pkg:pypi/poetry","ranges":[">=1.4.0 <2.3.3"],"fixed":["2.3.3"]}]}],"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).
