{"id":"CVE-2026-25547","summary":"Uncontrolled Resource Consumption in @isaacs/brace-expansion","details":"@isaacs/brace-expansion is a hybrid CJS/ESM TypeScript fork of brace-expansion. Prior to version 5.0.1, @isaacs/brace-expansion is vulnerable to a denial of service (DoS) issue caused by unbounded brace range expansion. When an attacker provides a pattern containing repeated numeric brace ranges, the library attempts to eagerly generate every possible combination synchronously. Because the expansion grows exponentially, even a small input can consume excessive CPU and memory and may crash the Node.js process. This issue has been patched in version 5.0.1.","aliases":["GHSA-7h2j-956f-4vf2"],"modified":"2026-03-31T08:14:18.364248Z","published":"2026-02-04T21:51:17.198Z","related":["CGA-h9mq-3c7r-hw5h","SUSE-SU-2026:1008-1","SUSE-SU-2026:1013-1","SUSE-SU-2026:1035-1","SUSE-SU-2026:1148-1","SUSE-SU-2026:20574-1","openSUSE-SU-2026:10168-1","openSUSE-SU-2026:10236-1","openSUSE-SU-2026:10250-1","openSUSE-SU-2026:10251-1","openSUSE-SU-2026:10252-1","openSUSE-SU-2026:10253-1","openSUSE-SU-2026:10254-1","openSUSE-SU-2026:10268-1","openSUSE-SU-2026:10269-1","openSUSE-SU-2026:10424-1","openSUSE-SU-2026:10428-1","openSUSE-SU-2026:20239-1","openSUSE-SU-2026:20261-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/25xxx/CVE-2026-25547.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-1333"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/25xxx/CVE-2026-25547.json"},{"type":"ADVISORY","url":"https://github.com/isaacs/brace-expansion/security/advisories/GHSA-7h2j-956f-4vf2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-25547"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/isaacs/brace-expansion","events":[{"introduced":"0"},{"fixed":"dc20357ee74ab18df00d596573764428ede66b3d"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"5.0.1"}]}}],"versions":["v1.0.0","v1.0.1","v1.1.0","v1.1.1","v1.1.10","v1.1.11","v1.1.2","v1.1.3","v1.1.4","v1.1.5","v1.1.6","v1.1.7","v1.1.8","v1.1.9","v2.0.0","v2.0.1","v3.0.0","v4.0.0","v4.0.1","v5.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-25547.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:N/VI:N/VA:H/SC:N/SI:N/SA:H"}]}
