{"id":"CVE-2026-69152","aliases":["GHSA-rgw5-rvv9-x895"],"url":"https://o3.security/vulnerability/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.","published":"2026-08-03T16:33:36.324Z","modified":"2026-09-14T11:56:35.903160755Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":{"score":0.00623,"percentile":0.48317,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"brace-expansion","fixedVersion":"1.1.18"},{"ecosystem":"npm","name":"brace-expansion","fixedVersion":"2.1.4"},{"ecosystem":"npm","name":"brace-expansion","fixedVersion":"3.0.6"},{"ecosystem":"npm","name":"brace-expansion","fixedVersion":"5.0.9"}],"fix":{"url":"https://github.com/juliangruber/brace-expansion/commit/139d015104e71433ad52a41d19467c48ecbb2c7d","label":"juliangruber/brace-expansion@139d015"},"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-14T11:56:35.903160755Z"}}
