{"cve":"CVE-2026-23949","nvd":{"published":"2026-01-20T01:15:57.723","modified":"2026-06-17T10:22:20.200","status":"Analyzed","description":"jaraco.context, an open-source software package that provides some useful decorators and context managers, has a Zip Slip path traversal vulnerability in the `jaraco.context.tarball()` function starting in version 5.2.0 and prior to version 6.1.0. The vulnerability may allow attackers to extract files outside the intended extraction directory when malicious tar archives are processed. The strip_first_component filter splits the path on the first `/` and extracts the second component, while allowing `../` sequences. Paths like `dummy_dir/../../etc/passwd` become `../../etc/passwd`. Note that this suffers from a nested tarball attack as well with multi-level tar files such as `dummy_dir/inner.tar.gz`, where the inner.tar.gz includes a traversal `dummy_dir/../../config/.env` that also gets translated to `../../config/.env`. Version 6.1.0 contains a patch for the issue.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N","score":8.6},"cwes":["CWE-22"],"references":["https://github.com/jaraco/jaraco.context/blob/main/jaraco/context/__init__.py#L74-L91","https://github.com/jaraco/jaraco.context/commit/7b26a42b525735e4085d2e994e13802ea339d5f9","https://github.com/jaraco/jaraco.context/security/advisories/GHSA-58pv-8j8x-9vj2","https://github.com/pypa/setuptools/blob/main/setuptools/_vendor/jaraco/context.py#L55-L76"],"products":["jaraco:jaraco.context"],"source":"nvd","synced_at":"2026-10-19T22:21:16.563232421+00:00"},"epss":{"cve":"CVE-2026-23949","score":0.00632,"percentile":0.50292,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-58pv-8j8x-9vj2","url":"https://osv.dev/vulnerability/GHSA-58pv-8j8x-9vj2","summary":"jaraco.context Has a Path Traversal Vulnerability","modified":"2026-09-10T03:50:32.597700920Z","packages":[{"ecosystem":"PyPI","name":"jaraco-context","purl":"pkg:pypi/jaraco-context","ranges":[">=5.2.0 <6.1.0"],"fixed":["6.1.0"]}]},{"id":"PYSEC-2026-1469","url":"https://osv.dev/vulnerability/PYSEC-2026-1469","summary":"jaraco.context Has a Path Traversal Vulnerability","modified":"2026-07-07T17:46:45.986582757Z","packages":[{"ecosystem":"PyPI","name":"jaraco-context","purl":"pkg:pypi/jaraco-context","ranges":[">=5.2.0 <6.1.0"],"fixed":["6.1.0"]}]}],"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).
