Attackers controlling a tool endpoint can return a 302 redirect to internal services, allowing the UTCP client to reach cloud metadata endpoints or internal HTTP services and return their response bodies to the caller.","categories":["Runtimes & languages"],"product":"python-utcp","vendor":"universal-tool-calling-protocol","ecosystem":"PyPI","affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-101060","source_modified_at":"2026-09-28T13:11:32.149Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"python-utcp","vendor":"universal-tool-calling-protocol","versions":[{"lessThan":"1.1.4","status":"affected","version":"0","versionType":"semver"},{"status":"unaffected","version":"1.1.4","versionType":"semver"}],"defaultStatus":"unaffected"},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-9qhg-99ww-9mqc","source_modified_at":"2026-08-25T23:58:07.304702919Z","fetched_at":"2026-10-23T18:55:00.935475Z","package":{"name":"utcp-http","ecosystem":"PyPI","purl":"pkg:pypi/utcp-http"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.1.4"}]}],"versions":["1.0.0","1.0.1","1.0.2","1.0.3","1.0.4","1.0.5","1.1.0","1.1.1","1.1.2","1.1.3"]}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-101060","source_modified_at":"2026-09-28T13:11:32.149Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"python-utcp","ecosystem":null},"version":"1.1.4","basis":"first unaffected version stated in the CVE record"},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-9qhg-99ww-9mqc","source_modified_at":"2026-08-25T23:58:07.304702919Z","fetched_at":"2026-10-23T18:55:00.935475Z","package":{"name":"utcp-http","ecosystem":"PyPI","purl":"pkg:pypi/utcp-http"},"version":"1.1.4"}],"cvss":8.4,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00182,"percentile":0.07397,"score_date":"2026-10-23"},"published_at":"2026-09-27T17:02:40.832Z","modified_at":"2026-09-28T13:11:32.149Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-101060","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-28T13:11:32.149Z"},{"source":"OSV","url":"https://osv.dev/vulnerability/GHSA-9qhg-99ww-9mqc","fetched_at":"2026-10-23T18:55:00.935475Z","source_modified_at":"2026-08-25T23:58:07.304702919Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-101060","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","OSV","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/universal-tool-calling-protocol/python-utcp/security/advisories/GHSA-9qhg-99ww-9mqc","tags":["exploit"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/python-utcp-before-1.1.4-ssrf-via-unvalidated-http-redirects","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-09-28T13:11:06.270676Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-09-28T13:11:32.149Z","content_hash":"8453b069222b4b6d1bc718456deac03ac089a47c4f2e02e6c33b4f93322b3669"}}
