Prior to 0.2.6, the tmp npm package contains a path traversal vulnerability that allows escaping the intended temporary directory when untrusted data flows into the prefix, postfix, or dir options. By embedding traversal sequences (e.g., ../) or path separators in these parameters, attackers can cause files to be created outside the configured temporary base directory at attacker-controlled locations with the privileges of the running process. This vulnerability affects applications that pass user-controlled data to tmp's file/directory creation functions without proper input sanitization. This vulnerability is fixed in 0.2.6.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:P","score":7.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:L","score":8.2},"cwes":["CWE-22"],"references":["https://github.com/raszi/node-tmp/security/advisories/GHSA-ph9p-34f9-6g65","https://github.com/raszi/node-tmp/security/advisories/GHSA-ph9p-34f9-6g65"],"products":["raszi:tmp"],"source":"nvd","synced_at":"2026-10-26T11:33:08.859761529+00:00"},"epss":{"cve":"CVE-2026-44705","score":0.00434,"percentile":0.37416,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-ph9p-34f9-6g65","url":"https://osv.dev/vulnerability/GHSA-ph9p-34f9-6g65","summary":"tmp has Path Traversal via unsanitized prefix/postfix that enables directory escape","modified":"2026-09-10T03:51:06.611832826Z","packages":[{"ecosystem":"npm","name":"tmp","purl":"pkg:npm/tmp","ranges":["<0.2.6"],"fixed":["0.2.6"]}]}],"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).
