{"schema":"threatline.record/2","record":{"id":"CVE-2026-58168","aliases":["GHSA-jg88-rvpc-qvxj","PYSEC-2026-4206"],"summary":"DeepTutor missing MCP tool authorization allows non-admin users to invoke unrestricted tools","details":"DeepTutor before version 1.4.10 contains an authorization bypass vulnerability that allows low-privilege users to invoke unrestricted MCP tools due to the allowed_mcp_tools function returning None instead of a denied result when mcp_tools is omitted from a user's grant in deeptutor/multi_user/tool_access.py. 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.","categories":["Libraries & packages"],"product":"deeptutor","vendor":"HKUDS","ecosystem":"pip","affected_ranges":[{"source":"GitHub Advisory Database","source_url":"https://github.com/advisories/GHSA-jg88-rvpc-qvxj","source_modified_at":"2026-10-02T18:27:30Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"ecosystem":"pip","name":"deeptutor"},"range":"< 1.4.10"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-58168","source_modified_at":"2026-07-14T21:34:54.832Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"DeepTutor","vendor":"HKUDS","versions":[{"version":"0","status":"affected","lessThan":"1.4.10","versionType":"semver"}],"defaultStatus":"unaffected"},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-jg88-rvpc-qvxj","source_modified_at":"2026-10-15T14:55:53.502546357Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"ecosystem":"PyPI","name":"deeptutor","purl":"pkg:pypi/deeptutor"},"ranges":[{"events":[{"introduced":"0"},{"fixed":"1.4.10"}],"type":"ECOSYSTEM"}],"versions":["1.4.0","1.4.0b0","1.4.1","1.4.2","1.4.3","1.4.4","1.4.5","1.4.6","1.4.7","1.4.8","1.4.9"]}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/advisories/GHSA-jg88-rvpc-qvxj","source_modified_at":"2026-10-02T18:27:30Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"ecosystem":"pip","name":"deeptutor"},"version":"1.4.10"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-58168","source_modified_at":"2026-07-14T21:34:54.832Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"DeepTutor","ecosystem":null},"version":"1.4.10","basis":"first unaffected version stated in the CVE record"},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-jg88-rvpc-qvxj","source_modified_at":"2026-10-15T14:55:53.502546357Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"ecosystem":"PyPI","name":"deeptutor","purl":"pkg:pypi/deeptutor"},"version":"1.4.10"}],"cvss":7.7,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00412,"percentile":0.3439,"score_date":"2026-10-23"},"published_at":"2026-06-30T15:52:22.032Z","modified_at":"2026-10-15T14:55:53.502546357Z","provenance":[{"source":"GitHub Advisory Database","url":"https://github.com/advisories/GHSA-jg88-rvpc-qvxj","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-02T18:27:30Z"},{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-58168","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-07-14T21:34:54.832Z"},{"source":"OSV","url":"https://osv.dev/vulnerability/GHSA-jg88-rvpc-qvxj","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-15T14:55:53.502546357Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-58168","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["GitHub Advisory Database","CVE List","OSV","EPSS"],"references":[{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-58168","source":"GitHub Advisory Database"},{"source":"CVE List","url":"https://github.com/HKUDS/DeepTutor/pull/579","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/HKUDS/DeepTutor/commit/90046374b3dcd4f8a866d2d64a64440bc08eb2ef","tags":["patch"]},{"source":"CVE List","url":"https://github.com/HKUDS/DeepTutor/releases/tag/v1.4.10","tags":["release-notes"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/deeptutor-insecure-default-grants-unrestricted-mcp-tool-access-to-non-admin-users","tags":["third-party-advisory"]},{"url":"https://github.com/advisories/GHSA-jg88-rvpc-qvxj","source":"GitHub Advisory Database"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"total","assessed_at":"2026-06-30T16:48:33.006727Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"ecosystem","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-15T14:55:53.502546357Z","content_hash":"1e2fbd8cba44a9121f1cc66f996b9a17def6067a607472a63247feb0e0c610ad"}}
