Prior to version 136, the esm.sh CDN service is vulnerable to path traversal during NPM package tarball extraction. An attacker can craft a malicious NPM package containing specially crafted file paths (e.g., package/../../tmp/evil.js). When esm.sh downloads and extracts this package, files may be written to arbitrary locations on the server, escaping the intended extraction directory. This issue has been patched in version 136.","state":0,"publishedAt":"2025-11-19T17:32:46.835+00:00","modifiedAt":"2025-11-20T14:09:44.277+00:00","affected":[{"ecosystem":"Vendor product","name":"esm.sh","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"esm-dev\",\n                    \"product\": \"esm.sh\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 136\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:N","score":8.2,"severity":"HIGH"}],"references":["https://github.com/esm-dev/esm.sh/security/advisories/GHSA-h3mw-4f23-gwpw","https://github.com/esm-dev/esm.sh/commit/9d77b88c320733ff6689d938d85d246a3af9af16"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2025-65025","license":"CVE Program Terms of Use","key":"cve-program:CVE-2025-65025","identifiers":["CVE-2025-65025"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
