The `expand()` function does not apply `maxLength` when constructing comma-alternative intermediate arrays or padded sequences, allowing attacker-controlled input to exhaust memory or block the event loop, resulting in a denial of service. This issue is due to an incomplete mitigation of CVE-2026-14257. ## Vendor advisories - **RHSA-2026:64817** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream EUS (v. 10.0) · released 2026-09-08 · [advisory](https://access.redhat.com/errata/RHSA-2026:64817) - **RHSA-2026:61374** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream EUS (v. 10.0) · released 2026-08-31 · [advisory](https://access.redhat.com/errata/RHSA-2026:61374) - **RHSA-2026:55541** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream (v. 10) · released 2026-08-17 · [advisory](https://access.redhat.com/errata/RHSA-2026:55541) - **RHSA-2026:52841** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream (v. 10) · released 2026-08-10 · [advisory](https://access.redhat.com/errata/RHSA-2026:52841) - **RHSA-2026:58819** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream (v. 10) · released 2026-08-24 · [advisory](https://access.redhat.com/errata/RHSA-2026:58819) - **RHSA-2026:54530** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream (v. 8) · released 2026-08-13 · [advisory](https://access.redhat.com/errata/RHSA-2026:54530) - **RHSA-2026:54371** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream (v. 8) · released 2026-08-12 · [advisory](https://access.redhat.com/errata/RHSA-2026:54371) - **RHSA-2026:62416** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream EUS (v.9.6) · released 2026-09-02 · [advisory](https://access.redhat.com/errata/RHSA-2026:62416) - **RHSA-2026:55601** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream (v. 9) · released 2026-08-17 · [advisory](https://access.redhat.com/errata/RHSA-2026:55601) - **RHSA-2026:55603** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream (v. 9) · released 2026-08-17 · [advisory](https://access.redhat.com/errata/RHSA-2026:55603) - **RHSA-2026:57590** · Red Hat · fixed in: Red Hat Enterprise Linux Extensions Channel (v. 10) · released 2026-08-20 · [advisory](https://access.redhat.com/errata/RHSA-2026:57590) - **Red Hat VEX** · Important · affected: Cryostat 4, Exploit Intelligence, Migration Toolkit for Applications 8, Migration Toolkit for Containers, Node HealthCheck Operator, OpenShift Lightspeed, … · no fix planned: Red Hat Ansible Automation Platform 2, Red Hat Directory Server 11, Red Hat Directory Server 12, Red Hat Directory Server 13, … · updated 2026-09-08 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-69152.json) **brace-expansion: DoS via unbounded intermediate arrays, bypassing the CVE-2026-14257 mitigation** — rated Important by Red Hat.
