Prior to version 1.9.7, the Enforcer is vulnerable to a path traversal attack where an attacker can use dot-dot (..) in the scope claim of a token to escape the intended directory restriction. This occurs because the library normalizes both the authorized path (from the token) and the requested path (from the application) before comparing them using startswith. This issue has been patched in version 1.9.7.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-22"],"references":["https://github.com/scitokens/scitokens/commit/2d1cc9e42bc944fe0bbc429b85d166e7156d53f9","https://github.com/scitokens/scitokens/pull/230","https://github.com/scitokens/scitokens/releases/tag/v1.9.7","https://github.com/scitokens/scitokens/security/advisories/GHSA-3x2w-63fp-3qvw"],"products":["scitokens:scitokens_library"],"source":"nvd","synced_at":"2026-10-19T22:28:18.033120106+00:00"},"epss":{"cve":"CVE-2026-32727","score":0.00525,"percentile":0.4452,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-3x2w-63fp-3qvw","url":"https://osv.dev/vulnerability/GHSA-3x2w-63fp-3qvw","summary":"SciTokens has an Authorization Bypass via Path Traversal in Scope Validation","modified":"2026-07-13T07:26:55.031361031Z","packages":[{"ecosystem":"PyPI","name":"scitokens","purl":"pkg:pypi/scitokens","ranges":["<1.9.7"],"fixed":["1.9.7"]}]},{"id":"PYSEC-2026-2277","url":"https://osv.dev/vulnerability/PYSEC-2026-2277","summary":"","modified":"2026-07-13T07:15:42.375575025Z","packages":[{"ecosystem":"PyPI","name":"scitokens","purl":"pkg:pypi/scitokens","ranges":["<1.9.7"],"fixed":["1.9.7"]}]}],"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).
