Attackers or prompt-injected content acting within a user session can enumerate and invoke any configured MCP tool, including filesystem, shell, and browser servers, gaining unauthorized access to sensitive deployment resources.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":7.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-862"],"references":["https://github.com/HKUDS/DeepTutor/commit/90046374b3dcd4f8a866d2d64a64440bc08eb2ef","https://github.com/HKUDS/DeepTutor/pull/579","https://github.com/HKUDS/DeepTutor/releases/tag/v1.4.10","https://www.vulncheck.com/advisories/deeptutor-insecure-default-grants-unrestricted-mcp-tool-access-to-non-admin-users","https://github.com/HKUDS/DeepTutor/pull/579"],"products":[],"source":"nvd","synced_at":"2026-10-25T23:44:33.281319194+00:00"},"epss":{"cve":"CVE-2026-58168","score":0.00412,"percentile":0.35179,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-jg88-rvpc-qvxj","url":"https://osv.dev/vulnerability/GHSA-jg88-rvpc-qvxj","summary":"DeepTutor missing MCP tool authorization allows non-admin users to invoke unrestricted tools","modified":"2026-10-15T14:55:53.502546357Z","packages":[{"ecosystem":"PyPI","name":"deeptutor","purl":"pkg:pypi/deeptutor","ranges":["<1.4.10"],"fixed":["1.4.10"]}]},{"id":"PYSEC-2026-4206","url":"https://osv.dev/vulnerability/PYSEC-2026-4206","summary":"DeepTutor missing MCP tool authorization allows non-admin users to invoke unrestricted tools","modified":"2026-10-15T14:45:05.890680056Z","packages":[{"ecosystem":"PyPI","name":"deeptutor","purl":"pkg:pypi/deeptutor","ranges":["<1.4.10"],"fixed":["1.4.10"]}]}],"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).
