{"id":"UBUNTU-CVE-2026-44705","details":"tmp is a temporary file and directory creator for node.js. 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.","modified":"2026-06-17T11:01:31.259606309Z","published":"2026-06-11T17:16:00Z","upstream":["CVE-2026-44705"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-44705"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-44705"},{"type":"REPORT","url":"https://github.com/raszi/node-tmp/security/advisories/GHSA-ph9p-34f9-6g65"}],"affected":[{"package":{"name":"node-tmp","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/node-tmp?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0.25-1","0.0.28-1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.0.28-1","binary_name":"node-tmp"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-44705.json"}},{"package":{"name":"node-tmp","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/node-tmp?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0.31-1"],"ecosystem_specific":{"binaries":[{"binary_name":"node-tmp","binary_version":"0.0.31-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-44705.json"}},{"package":{"name":"node-tmp","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/node-tmp?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0.33+dfsg-2","0.1.0+dfsg-2","0.1.0+dfsg-3","0.1.0+dfsg-6"],"ecosystem_specific":{"binaries":[{"binary_name":"node-tmp","binary_version":"0.1.0+dfsg-6"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-44705.json"}},{"package":{"name":"node-tmp","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/node-tmp?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.2.1+dfsg-1","0.2.1+dfsg-2","0.2.1+dfsg+~0.2.2-1"],"ecosystem_specific":{"binaries":[{"binary_name":"node-tmp","binary_version":"0.2.1+dfsg+~0.2.2-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-44705.json"}},{"package":{"name":"node-tmp","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/node-tmp?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.2.2+dfsg+~0.2.3-1"],"ecosystem_specific":{"binaries":[{"binary_name":"node-tmp","binary_version":"0.2.2+dfsg+~0.2.3-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-44705.json"}},{"package":{"name":"node-tmp","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/node-tmp?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.2.2+dfsg+~0.2.3-1","0.2.2+dfsg+~0.2.3-1.1"],"ecosystem_specific":{"binaries":[{"binary_name":"node-tmp","binary_version":"0.2.2+dfsg+~0.2.3-1.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-44705.json"}},{"package":{"name":"node-tmp","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/node-tmp?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.2.2+dfsg+~0.2.3-1.1","0.2.5+dfsg+~0.2.6-1","0.2.5+dfsg+~0.2.6-2"],"ecosystem_specific":{"binaries":[{"binary_version":"0.2.5+dfsg+~0.2.6-2","binary_name":"node-tmp"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-44705.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"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"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:L"},{"type":"Ubuntu","score":"medium"}]}
