Affected: juliangruber brace-expansion

The brace-expansion library generates arbitrary strings containing a common prefix and suffix. From 5.0.0 to before 5.0.6, the max option was being applied too late. When expanding a single large numeric range like {1..10000000}, the sequence generation loop generates all 10 million intermediate elements before the max limit is applied With max=10, the output is correctly limited to 10 items, but the process still allocates ~505 MB and spends ~800ms building the full intermediate array. This vulnerability is fixed in 5.0.6.

Affected: npm: brace-expansion

The `max` option was being applied too late:

When expanding a single large numeric range like `{1..10000000}`, the sequence generation loop generates all 10 million intermediate elements before the `max` limit is applied With `max=10`, the output is correctly limited to 10 items, but the process still allocates `~505 MB` and spends `~800ms` building the full intermediate array.

### Workaround

Ensure the string to be expanded doesn't contain more values than the desired `max` item count.
