Affected: AlmaLinux:10: nodejs-docs

Node.js is a platform built on Chrome's JavaScript runtime \ for easily building fast, scalable network applications. \ Node.js uses an event-driven, non-blocking I/O model that \ makes it lightweight and efficient, perfect for data-intensive \ real-time applications that run across distributed devices.

Package npm version 11.8.0-r0 fixes 1 vulnerabilities: CVE-2026-25547

@isaacs/brace-expansion is a hybrid CJS/ESM TypeScript fork of brace-expansion. Prior to version 5.0.1, @isaacs/brace-expansion is vulnerable to a denial of service (DoS) issue caused by unbounded brace range expansion. When an attacker provides a pattern containing repeated numeric brace ranges, the library attempts to eagerly generate every possible combination synchronously. Because the expansion grows exponentially, even a small input can consume excessive CPU and memory and may crash the Node.js process. This issue has been patched in version 5.0.1.

Affected: npm: @isaacs/brace-expansion

### Summary

`@isaacs/brace-expansion` is vulnerable to a Denial of Service (DoS) issue caused by unbounded brace range expansion. When an attacker provides a pattern containing repeated numeric brace ranges, the library attempts to eagerly generate every possible combination synchronously. Because the expansion grows exponentially, even a small input can consume excessive CPU and memory and may crash the Node.js process.

### Details

The vulnerability occurs because `@isaacs/brace-expansion` expands brace expressions without any upper bound or complexity limit. Expansion is performed eagerly and synchronously, meaning the full result set is generated before returning control to the caller.

For example, the following input:

``` {0..99}{0..99}{0..99}{0..99}{0..99} ```

produces:

``` 100^5 = 10,000,000,000 combinations ```

This exponential growth can quickly overwhelm the event loop and heap memory, resulting in process termination.

### Proof of Concept

The following script reliably triggers the issue.

Create `poc.js`:

```js const { expand } = require('@isaacs/brace-expansion');

const pattern = '{0..99}{0..99}{0..99}{0..99}{0..99}';

console.log('Starting expansion...'); expand(pattern); ```

Run it:

```bash node poc.js ```

The process will freeze and typically crash with an error such as:

``` FATAL ERROR: JavaScript heap out of memory ```

### Impact

This is a denial of service vulnerability. Any application or downstream dependency that uses `@isaacs/brace-expa…
