Source description

As published by the source; long descriptions are shortened.

AngularJS lets users write client-side web applications. The package angular after 1.7.0 is vulnerable to Regular Expression Denial of Service (ReDoS) by providing a custom locale rule that makes it possible to assign the parameter in posPre: ' '.repeat() of NUMBERFORMATS.PATTERNS[1].posPre with a very high value. Note: 1. This package has been deprecated and is no longer maintained. 2. The vulnerable versions are 1.7.0 and higher.

# Patch Next advisory brief: CVE-2022-25844

Advisory: angular vulnerable to regular expression denial of service (ReDoS)
IDs: CVE-2022-25844, GHSA-m2h2-264f-f486
Record: https://patchnext.com/advisories/cve-2022-25844 (revision 2, source checked 26 Oct 2026, 12:38 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.3)
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.

## Affected components
- npm angular: affected >= 1.7.0

## Suggested inspection (read-only)
- `npm ls angular --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 angular.
- 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.
