CVE-2025-64756 — glob CLI: Command injection via -c/--cmd executes matches with shell:true

Affected: isaacs node-glob

Glob matches files using patterns the shell uses. Starting in version 10.2.0 and prior to versions 10.5.0 and 11.1.0, the glob CLI contains a command injection vulnerability in its -c/--cmd option that allows arbitrary command execution when processing files with malicious names. When glob -c <command> <patterns> are used, matched filenames are passed to a shell with shell: true, enabling shell metacharacters in filenames to trigger command injection and achieve arbitrary code execution under the user or CI account privileges. This issue has been patched in versions 10.5.0 and 11.1.0.

GHSA-23c5-xmqv-rm74 — minimatch ReDoS: nested *() extglobs generate catastrophically backtracking regular expressions

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…
