{"cve":"CVE-2026-30625","nvd":{"published":"2026-04-15T16:16:36.787","modified":"2026-06-17T10:32:50.503","status":"Deferred","description":"Upsonic 0.71.6 contains a remote code execution vulnerability in its MCP server/task creation functionality. The application allows users to define MCP tasks with arbitrary command and args values. Although an allowlist exists, certain allowed commands (npm, npx) accept argument flags that enable execution of arbitrary OS commands. Maliciously crafted MCP tasks may lead to remote code execution with the privileges of the Upsonic process. In version 0.72.0 Upsonic added a warning about using Stdio servers being able to execute commands directly on the machine.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-77"],"references":["https://github.com/Upsonic/Upsonic/commit/855053fce0662227d9246268ff4a0844b481a305","https://www.ox.security/blog/mcp-supply-chain-advisory-rce-vulnerabilities-across-the-ai-ecosystem/"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:30:49.762551342+00:00"},"epss":{"cve":"CVE-2026-30625","score":0.00974,"percentile":0.62071,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-cw73-5f7h-m4gv","url":"https://osv.dev/vulnerability/GHSA-cw73-5f7h-m4gv","summary":"Upsonic: remote code execution vulnerability in its MCP server/task creation functionality","modified":"2026-06-29T12:26:19.840980901Z","packages":[{"ecosystem":"PyPI","name":"upsonic","purl":"pkg:pypi/upsonic","ranges":["<0.72.0"],"fixed":["0.72.0"]}]},{"id":"PYSEC-2026-559","url":"https://osv.dev/vulnerability/PYSEC-2026-559","summary":"Upsonic: remote code execution vulnerability in its MCP server/task creation functionality","modified":"2026-07-01T20:23:10.875949Z","packages":[{"ecosystem":"PyPI","name":"upsonic","purl":"pkg:pypi/upsonic","ranges":["<0.72.0"],"fixed":["0.72.0"]}]}],"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).
