Summary
brace-expansion: DoS via uncontrolled recursion on nested brace groups causing stack exhaustion
Details

The brace-expansion library generates arbitrary strings containing a common prefix and suffix. Prior to 1.1.20, 2.1.6, 3.0.8, and 5.0.11, deeply nested brace groups cause expand_() to recurse once per nesting level at comma-member and single-set expansion sites, exhausting the native stack before output limits can apply and potentially terminating the Node.js process. expand_ performs uncontrolled recursion for nested brace alternatives and single-part sets. deeply nested brace groups supplied as an untrusted pattern. expand_ is affected. expand is affected. Comma members is affected. Single set is affected. native stack exhaustion during nested sub-expansion. process-terminating denial of service. This issue is fixed in versions 1.1.20, 2.1.6, 3.0.8, and 5.0.11.
