{"id":"UBUNTU-CVE-2026-102278","details":"The brace-expansion library generates arbitrary strings containing a common prefix and suffix. Prior to 1.1.20, 2.1.6, 3.0.8, and 5.0.11, deeply nested brace groups cause expand_() to recurse once per nesting level at comma-member and single-set expansion sites, exhausting the native stack before output limits can apply and potentially terminating the Node.js process. expand_ performs uncontrolled recursion for nested brace alternatives and single-part sets. deeply nested brace groups supplied as an untrusted pattern. expand_ is affected. expand is affected. Comma members is affected. Single set is affected. native stack exhaustion during nested sub-expansion. process-terminating denial of service. This issue is fixed in versions 1.1.20, 2.1.6, 3.0.8, and 5.0.11.","modified":"2026-09-29T23:41:45.589778086Z","published":"2026-09-29T00:00:00Z","upstream":["CVE-2026-102278"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-102278"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-102278"},{"type":"REPORT","url":"https://github.com/juliangruber/brace-expansion/commit/1efee7c397c191da6287a78ec19512476a966a7b"},{"type":"REPORT","url":"https://github.com/juliangruber/brace-expansion/commit/935d78f32f335b2ff76578e5c5e877d31ae9888c"},{"type":"REPORT","url":"https://github.com/juliangruber/brace-expansion/commit/de84f144e9816f30e25fc8179e2e1249ab6df0db"},{"type":"REPORT","url":"https://github.com/juliangruber/brace-expansion/security/advisories/GHSA-qhr7-859c-m2p7"}],"affected":[{"package":{"name":"node-brace-expansion","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/node-brace-expansion?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.8-1"],"ecosystem_specific":{"binaries":[{"binary_name":"node-brace-expansion","binary_version":"1.1.8-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-102278.json"}},{"package":{"name":"node-brace-expansion","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/node-brace-expansion?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.8-1","1.1.11-1"],"ecosystem_specific":{"binaries":[{"binary_name":"node-brace-expansion","binary_version":"1.1.11-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-102278.json"}},{"package":{"name":"node-brace-expansion","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/node-brace-expansion?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.0.0-1","2.0.1-1"],"ecosystem_specific":{"binaries":[{"binary_name":"node-brace-expansion","binary_version":"2.0.1-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-102278.json"}},{"package":{"name":"node-brace-expansion","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/node-brace-expansion?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.0.1-2","2.0.1+~1.1.0-1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.0.1+~1.1.0-1","binary_name":"node-brace-expansion"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-102278.json"}},{"package":{"name":"node-brace-expansion","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/node-brace-expansion?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.0.1+~1.1.0-2"],"ecosystem_specific":{"binaries":[{"binary_name":"node-brace-expansion","binary_version":"2.0.1+~1.1.0-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-102278.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"}]}
