Source description

As published by the source; long descriptions are shortened.

All versions of the package bun are vulnerable to Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in the $ shell API due to improper neutralization of user input. An attacker can exploit this by providing specially crafted input that includes command-line arguments or shell metacharacters, leading to unintended command execution.

# Patch Next advisory brief: CVE-2025-8022

Advisory: bun vulnerable to OS Command Injection
IDs: CVE-2025-8022, GHSA-4j66-8f4r-3pjx
Record: https://patchnext.com/advisories/cve-2025-8022 (revision 3, source checked 26 Oct 2026, 17:09 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.4)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.
Status: WITHDRAWN upstream. Do not act on this record without new evidence.

## Affected components
- npm bun: affected <= 1.1.39

## Suggested inspection (read-only)
- `npm ls bun --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on bun.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
