### brace-expansion: DoS via unbounded expansion length causing an
out-of-memory process crash
[CVE-2026-14257](https://nvd.nist.gov/vuln/detail/CVE-2026-14257) /

#### Details
##### Summary

`expand()` bounds the *number* of results it produces (the `max` option,
`100_000` by default) but not their *length*. By chaining many brace
groups,
an attacker keeps the result count under `max` while making every result
grow
with the number of groups. Building `max` long results — plus the
intermediate
arrays combined at each brace group — exhausts memory and crashes the
Node
process with an **uncatchable** out-of-memory error. `try/catch` around
`expand()` does not help: the fatal error terminates the process.

A ~7.5 KB input (`'{a,b}'.repeat(1500)`) is enough to crash a default
Node
process.

##### Details

For `N` chained brace groups such as `'{a,b}'.repeat(N)`:

- the result count is `2^N`, immediately capped at `max` (`100_000`), so
the
  `max` protection appears to hold, but
- each result is `N` characters long, so the total output size is... (continued)
