{"id":"UBUNTU-CVE-2026-73566","details":"node-tar is a tar archive manipulation library for Node.js. Prior to 7.5.21, node-tar's filesFilter in src/list.ts uses the recursive mapHas helper to walk an archive entry path upward with path.dirname() and no segment cap when tar.t(...) or tar.x(...) receives a non-empty member-selection list. A crafted GNU L or PAX x long-path header with thousands of slash-separated segments reaches this.filter(entry.path, entry) in Parser[CONSUMEHEADER] in src/parse.ts before Unpack[CHECKPATH] applies maxDepth, causing an uncatchable RangeError stack overflow that terminates asynchronous and streaming Node.js consumers. This issue is fixed in version 7.5.21.","modified":"2026-08-19T13:34:33.274489230Z","published":"2026-08-13T18:18:00Z","upstream":["CVE-2026-73566"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-73566"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-73566"},{"type":"REPORT","url":"https://github.com/isaacs/node-tar/security/advisories/GHSA-r292-9mhp-454m"}],"affected":[{"package":{"name":"node-tar","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/node-tar?arch=source&distro=esm-infra-legacy%2Ftrusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.1.18-1","0.1.18-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"node-tar","binary_version":"0.1.18-1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-73566.json"}},{"package":{"name":"node-tar","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/node-tar?arch=source&distro=esm-apps%2Fxenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.0.3-2","1.0.3-2ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"node-tar","binary_version":"1.0.3-2ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-73566.json"}},{"package":{"name":"node-tar","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/node-tar?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.2.1-1"],"ecosystem_specific":{"binaries":[{"binary_name":"node-tar","binary_version":"2.2.1-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-73566.json"}},{"package":{"name":"node-tar","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/node-tar?arch=source&distro=esm-apps%2Ffocal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.4.10+ds1-2","4.4.10+ds1-2ubuntu1","4.4.10+ds1-2ubuntu1+esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"4.4.10+ds1-2ubuntu1+esm1","binary_name":"node-tar"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-73566.json"}},{"package":{"name":"node-tar","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/node-tar?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.1.7+~cs11.3.10-1","6.1.11+~cs11.3.10-1","6.1.11+ds1+~cs6.0.6-1"],"ecosystem_specific":{"binaries":[{"binary_name":"node-tar","binary_version":"6.1.11+ds1+~cs6.0.6-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-73566.json"}},{"package":{"name":"node-tar","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/node-tar?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.1.13+~cs7.0.5-1","6.1.13+~cs7.0.5-3"],"ecosystem_specific":{"binaries":[{"binary_version":"6.1.13+~cs7.0.5-3","binary_name":"node-tar"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-73566.json"}},{"package":{"name":"node-tar","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/node-tar?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.2.1+~cs7.0.8-1","6.2.1+ds1+~cs6.1.13-6","6.2.1+ds1+~cs6.1.13-7","6.2.1+ds1+~cs6.1.13-10"],"ecosystem_specific":{"binaries":[{"binary_name":"node-tar","binary_version":"6.2.1+ds1+~cs6.1.13-10"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-73566.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
