Prior to 1.83.7-stable, LiteLLM Skills archive extraction did not sufficiently validate file paths from uploaded skill ZIP archives, allowing an authenticated user with access to LiteLLM LLM API routes or a key whose allowed_routes includes /v1/skills, anthropic_routes, or llm_api_routes to upload a crafted skill archive containing path traversal entries that could be written outside the intended extraction or staging directory. This issue is fixed in version 1.83.7-stable.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N","score":6.1},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","score":6.5},"cwes":["CWE-22"],"references":["https://github.com/BerriAI/litellm/commit/6a15adcd64137d37f73dee76dfe7481f8c2d9196","https://github.com/BerriAI/litellm/pull/25475","https://github.com/BerriAI/litellm/releases/tag/v1.83.7-stable","https://github.com/BerriAI/litellm/security/advisories/GHSA-5jmr-gcrj-2c9q"],"products":["litellm:litellm"],"source":"nvd","synced_at":"2026-10-25T17:50:06.907763985+00:00"},"epss":{"cve":"CVE-2026-59820","score":0.00587,"percentile":0.47777,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-5jmr-gcrj-2c9q","url":"https://osv.dev/vulnerability/GHSA-5jmr-gcrj-2c9q","summary":"LiteLLM: Arbitrary file write via path traversal in Skills archive extraction","modified":"2026-09-10T03:51:10.470938459Z","packages":[{"ecosystem":"PyPI","name":"litellm","purl":"pkg:pypi/litellm","ranges":["<1.83.7"],"fixed":["1.83.7"]}]},{"id":"PYSEC-2026-3477","url":"https://osv.dev/vulnerability/PYSEC-2026-3477","summary":"LiteLLM: Arbitrary file write via path traversal in Skills archive extraction","modified":"2026-07-23T15:00:15.302353609Z","packages":[{"ecosystem":"PyPI","name":"litellm","purl":"pkg:pypi/litellm","ranges":["<1.83.7"],"fixed":["1.83.7"]}]}],"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).
