Affected: octokit endpoint.js

@octokit/endpoint turns REST API endpoints into generic request options. Starting in version 4.1.0 and prior to version 10.1.3, by crafting specific `options` parameters, the `endpoint.parse(options)` call can be triggered, leading to a regular expression denial-of-service (ReDoS) attack. This causes the program to hang and results in high CPU utilization. The issue occurs in the `parse` function within the `parse.ts` file of the npm package `@octokit/endpoint`. Version 10.1.3 contains a patch for the issue.

 https://cve.radiocsirt.org/vuln/ghsa-23c5-xmqv-rm74 GHSA-23c5-xmqv-rm74 — minimatch ReDoS: nested *() extglobs generate catastrophically backtracking regular expressions 2026-10-05T10:27:15.656829+00:00

Affected: npm: minimatch

### Summary

Nested `*()` extglobs produce regexps with nested unbounded quantifiers (e.g. `(?:(?:a|b)*)*`), which exhibit catastrophic backtracking in V8. With a 12-byte pattern `*(*(*(a|b)))` and an 18-byte non-matching input, `minimatch()` stalls for over 7 seconds. Adding a single nesting level or a few input characters pushes this to minutes. This is the most severe finding: it is triggered by the default `minimatch()` API with no special options, and the minimum viable pattern is only 12 bytes. The same issue affects `+()` extglobs equally.

### Details

The root cause is in `AST.toRegExpSource()` at [`src/ast.ts#L598`](https://github.com/isaacs/minimatch/blob/v10.2.2/src/ast.ts#L598). For the `*` extglob type, the close token emitted is `)*` or `)?`, wrapping the recursive body in `(?:...)*`. When extglobs are nested, each level adds another `*` quantifier around the previous group:

```typescript : this.type === '*' && bodyDotAllowed ? `)?` : `)${this.type}` ```

This produces the following regexps:

| Pattern | Generated regex | |----------------------|------------------------------------------| | `*(a\|b)` | `/^(?:a\|b)*$/` | | `*(*(a\|b))` | `/^(?:(?:a\|b)*)*$/` | | `*(*(*(a\|b)))` | `/^(?:(?:(?:a\|b)*)*)*$/` | | `*(*(*(*(a\|b))))` | `/^(?:(?:(?:(?:a\|b)*)*)*)*$/` |

These are textbook nested-quantifier patterns. Against an input o…
