{"cve":"CVE-2026-104853","nvd":{"published":"2026-10-02T17:17:03.920","modified":"2026-10-02T18:17:01.837","status":"Undergoing Analysis","description":"Nx is a monorepo solution for TypeScript and polyglot codebases. From 13.10.0 until 22.7.10 and 23.2.1, Nx migration planning reads the nx-migrations.migrations value from a target package manifest without validating that it is a contained relative path. A hostile direct dependency or a package introduced through a trusted package's packageGroup can supply .. segments or an absolute path, causing nx migrate to join an escaping destination onto its temporary directory. The migration archive can then write attacker-controlled bytes outside the temporary directory, while opening the destination stream can truncate an existing writable file even when no archive entry matches. This occurs during migration planning before review of the migration list or use of --run-migrations; the vulnerable installed Nx copy is reached when the normal nx@latest handoff is bypassed with NX_USE_LOCAL, NX_MIGRATE_USE_LOCAL, NX_MIGRATE_CLI_VERSION, --run-id, or fallback after a temporary-install failure. This issue is fixed in versions 22.7.10 and 23.2.1.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:P/VC:L/VI:H/VA:L/SC:N/SI:N/SA:N","score":5.8},"cvss_v3":null,"cwes":["CWE-22","CWE-73"],"references":["https://github.com/nrwl/nx/commit/38cd82a0c05e8212e538bdb87ccb198d6504e58f","https://github.com/nrwl/nx/commit/95474ab457e8e1dbdbefad29040c166105a8fb90","https://github.com/nrwl/nx/commit/de37c5ebd1852fac700d70726326236ac398af3f","https://github.com/nrwl/nx/pull/36887","https://github.com/nrwl/nx/releases/tag/22.7.10"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:57:46.668721662+00:00"},"epss":{"cve":"CVE-2026-104853","score":0.00172,"percentile":0.06543,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-hrvq-x7jp-36xv","url":"https://osv.dev/vulnerability/GHSA-hrvq-x7jp-36xv","summary":"Nx: Path traversal in nx migrate package-migrations extraction","modified":"2026-10-05T23:45:08.231333021Z","packages":[{"ecosystem":"npm","name":"nx","purl":"pkg:npm/nx","ranges":[">=13.10.0 <22.7.10"],"fixed":["22.7.10"]},{"ecosystem":"npm","name":"nx","purl":"pkg:npm/nx","ranges":[">=23.0.0 <23.2.1"],"fixed":["23.2.1"]}]}],"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).
