{"cve":"CVE-2025-64481","nvd":{"published":"2025-11-07T21:15:42.010","modified":"2026-06-17T09:54:26.210","status":"Deferred","description":"Datasette is an open source multi-tool for exploring and publishing data. In versions 0.65.1 and below and 1.0a0 through 1.0a19, deployed instances of Datasette include an open redirect vulnerability. Hits to the path //example.com/foo/bar/ (the trailing slash is required) will redirect the user to https://example.com/foo/bar. This problem has been patched in both Datasette 0.65.2 and 1.0a21. To workaround this issue, if Datasette is running behind a proxy, that proxy could be configured to replace // with / in incoming request URLs.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U","score":2.7},"cvss_v3":null,"cwes":["CWE-601"],"references":["https://github.com/simonw/datasette/commit/f257ca6edb64848c3b04b54d41e347c54fe57c05","https://github.com/simonw/datasette/issues/2429","https://github.com/simonw/datasette/security/advisories/GHSA-w832-gg5g-x44m"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:14:53.307938015+00:00"},"epss":{"cve":"CVE-2025-64481","score":0.00411,"percentile":0.35419,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-w832-gg5g-x44m","url":"https://osv.dev/vulnerability/GHSA-w832-gg5g-x44m","summary":"Open redirect endpoint in Datasette","modified":"2026-05-19T20:30:23.793299560Z","packages":[{"ecosystem":"PyPI","name":"datasette","purl":"pkg:pypi/datasette","ranges":["<0.65.2"],"fixed":["0.65.2"]},{"ecosystem":"PyPI","name":"datasette","purl":"pkg:pypi/datasette","ranges":[">=1.0a0 <1.0a21"],"fixed":["1.0a21"]}]},{"id":"PYSEC-2025-73","url":"https://osv.dev/vulnerability/PYSEC-2025-73","summary":"","modified":"2026-05-19T05:15:05.313924531Z","packages":[{"ecosystem":"PyPI","name":"datasette","purl":"pkg:pypi/datasette","ranges":[],"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).
