{"id":"DEBIAN-CVE-2026-33750","details":"The brace-expansion library generates arbitrary strings containing a common prefix and suffix. Prior to versions 5.0.5, 3.0.2, 2.0.3, and 1.1.13, a brace pattern with a zero step value (e.g., `{1..2..0}`) causes the sequence generation loop to run indefinitely, making the process hang for seconds and allocate heaps of memory. Versions 5.0.5, 3.0.2, 2.0.3, and 1.1.13 fix the issue. As a workaround, sanitize strings passed to `expand()` to ensure a step value of `0` is not used.","modified":"2026-09-14T17:03:08.480733261Z","published":"2026-03-27T15:16:57.297Z","upstream":["CVE-2026-33750"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-33750"}],"affected":[{"package":{"name":"node-brace-expansion","ecosystem":"Debian:12","purl":"pkg:deb/debian/node-brace-expansion?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.0.1+~1.1.0-1","2.0.1+~1.1.0-2","2.0.1-2","2.0.3+~1.1.2-1","2.0.3+~1.1.2-2","2.0.3+~1.1.2-3","2.1.4+~1.1.2-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-33750.json"}},{"package":{"name":"node-brace-expansion","ecosystem":"Debian:13","purl":"pkg:deb/debian/node-brace-expansion?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.0.1+~1.1.0-2","2.0.3+~1.1.2-1","2.0.3+~1.1.2-2","2.0.3+~1.1.2-3","2.1.4+~1.1.2-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-33750.json"}},{"package":{"name":"node-brace-expansion","ecosystem":"Debian:14","purl":"pkg:deb/debian/node-brace-expansion?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.0.3+~1.1.2-1"}]}],"versions":["2.0.1+~1.1.0-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-33750.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"}]}
