{"cve":"CVE-2026-28414","nvd":{"published":"2026-02-27T22:16:24.330","modified":"2026-06-17T10:28:34.737","status":"Analyzed","description":"Gradio is an open-source Python package designed for quick prototyping. Prior to version 6.7, Gradio apps running on Window with Python 3.13+ are vulnerable to an absolute path traversal issue that enables unauthenticated attackers to read arbitrary files from the file system. Python 3.13+ changed the definition of `os.path.isabs` so that root-relative paths like `/windows/win.ini` on Windows are no longer considered absolute paths, resulting in a vulnerability in Gradio's logic for joining paths safely. This can be exploited by unauthenticated attackers to read arbitrary files from the Gradio server, even when Gradio is set up with authentication. Version 6.7 fixes the issue.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-22","CWE-36"],"references":["https://github.com/gradio-app/gradio/security/advisories/GHSA-39mp-8hj3-5c49"],"products":["gradio_project:gradio"],"source":"nvd","synced_at":"2026-10-19T22:24:17.937441719+00:00"},"epss":{"cve":"CVE-2026-28414","score":0.03059,"percentile":0.87601,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-39mp-8hj3-5c49","url":"https://osv.dev/vulnerability/GHSA-39mp-8hj3-5c49","summary":"Gradio is Vulnerable to Absolute Path Traversal on Windows with Python 3.13+","modified":"2026-06-06T00:30:08.740526290Z","packages":[{"ecosystem":"PyPI","name":"gradio","purl":"pkg:pypi/gradio","ranges":["<6.7.0"],"fixed":["6.7.0"]}]},{"id":"PYSEC-2026-64","url":"https://osv.dev/vulnerability/PYSEC-2026-64","summary":"","modified":"2026-05-20T09:19:02.056278Z","packages":[{"ecosystem":"PyPI","name":"gradio","purl":"pkg:pypi/gradio","ranges":["<6.7.0"],"fixed":["6.7.0"]}]}],"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).
