NVD Description

Note: Versions mentioned in the description apply only to the upstream npm package and not the npm package as distributed by Oracle. See How to fix? for Oracle:9 relevant fixed versions and status.

brace-expansion through 5.0.6 is vulnerable to denial of service. The expand() function exhibits exponential-time complexity in the number of consecutive non-expanding '{}' brace groups. An attacker who passes a crafted string to expand(), directly or transitively, can cause significant CPU consumption and event-loop blocking. The max option does not mitigate this, as it bounds the output size rather than the recursion work.
