Answer in brief
CVE-2026-102276 records a High severity (CVSS 7.5) vulnerability in brace-expansion: DoS via uncontrolled recursion in parseCommaParts causing stack exhaustion. The current sources do not mark it as known exploited. The current feed maps juliangruber/brace-expansion (generic). Check affected ranges and fixed versions before updating.

The brace-expansion library generates arbitrary strings containing a common prefix and suffix. Prior to 1.1.19, 2.1.5, 3.0.7, and 5.0.10, crafted brace patterns can exhaust the native stack in parseCommaParts because parseCommaParts recursively processes the remainder once per brace group and uses push.apply to pass every element of a very large comma-part array as a function argument. Patterns containing many comma-separated brace groups trigger the recursive path, while the large array triggers the argument-array path without deep recursion. These paths cause recursive and argument-array native stack exhaustion before max or maxLength can limit output, potentially terminating the Node.js process in a process-terminating denial of service. This issue is fixed in versions 1.1.19, 2.1.5, 3.0.7, and 5.0.10.
