{"id":"CVE-2026-69152","summary":"brace-expansion: DoS via unbounded intermediate arrays, bypassing the CVE-2026-14257 mitigation","details":"The brace-expansion library generates arbitrary strings containing a common prefix and suffix. Prior to 1.1.18, 2.1.4, 3.0.6, and 5.0.9, expand() does not apply maxLength while constructing comma-alternative intermediate arrays or padded sequences, allowing attacker-controlled input to exhaust memory or block the event loop. The fix for CVE-2026-14257 is bypassed by the vulnerability. This issue is fixed in versions 1.1.18, 2.1.4, 3.0.6, and 5.0.9.","aliases":["GHSA-rgw5-rvv9-x895"],"modified":"2026-08-07T03:46:42.875491367Z","published":"2026-08-03T16:33:36.324Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-400","CWE-770"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/69xxx/CVE-2026-69152.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/69xxx/CVE-2026-69152.json"},{"type":"ADVISORY","url":"https://github.com/juliangruber/brace-expansion/security/advisories/GHSA-rgw5-rvv9-x895"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-69152"},{"type":"FIX","url":"https://github.com/juliangruber/brace-expansion/commit/139d015104e71433ad52a41d19467c48ecbb2c7d"},{"type":"FIX","url":"https://github.com/juliangruber/brace-expansion/commit/1e30c930238d7162802d88a94189182def178dac"},{"type":"FIX","url":"https://github.com/juliangruber/brace-expansion/commit/688a99eeaab02627c2b89ba8ba4821fecfa659cf"},{"type":"FIX","url":"https://github.com/juliangruber/brace-expansion/commit/cb4b9e47cc2ec777c14b2b4492fb431a56f6a031"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/juliangruber/brace-expansion","events":[{"introduced":"0"},{"fixed":"758fcd6d188a95c2342818519c77b8c06794552b"},{"introduced":"0b6a022491103b806770bc037654744bef3e63be"},{"fixed":"b25213dff0446d622f97d736420b9830ee1abc32"},{"introduced":"b01a637b0578a7c59acc7d8386f11f8d0710b512"},{"fixed":"da500e1736f2e1afe615f5f588fb87252de484b1"},{"introduced":"6a39bdddcf944374b475d99b0e8292d3727c7ebe"},{"fixed":"fbcf8ec75b88c79374b4aac06559b1a5288a1223"},{"fixed":"139d015104e71433ad52a41d19467c48ecbb2c7d"},{"fixed":"1e30c930238d7162802d88a94189182def178dac"},{"fixed":"688a99eeaab02627c2b89ba8ba4821fecfa659cf"},{"fixed":"cb4b9e47cc2ec777c14b2b4492fb431a56f6a031"}],"database_specific":{"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:juliangruber:brace-expansion:*:*:*:*:*:node.js:*:*","extracted_events":[{"introduced":"0"},{"fixed":"1.1.18"},{"introduced":"2.0.0"},{"fixed":"2.1.4"},{"introduced":"3.0.0"},{"fixed":"3.0.6"},{"introduced":"4.0.0"},{"fixed":"5.0.9"}]}}],"versions":["v1.1.17","v2.1.3","v1.1.16","v2.1.2","v3.0.4","v3.0.3","v3.0.2","v5.0.8","v2.1.1","v1.1.15","v5.0.7","v1.1.14","v2.1.0","v5.0.6","v2.0.3","v1.1.13","v3.0.1","v2.0.2","v1.1.12","v5.0.5","v5.0.4","v5.0.3","v5.0.2","v4.0.1","v1.1.11","v2.0.1","v3.0.0","v4.0.0","v2.0.0","v1.1.10","v1.1.9","v1.1.8","v1.1.7","v1.1.6","v1.1.5","v1.1.4","v1.1.3","v1.1.2","v1.1.1","v1.1.0","v1.0.1","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-69152.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
