# Patch Next advisory brief: CVE-2026-45325

Advisory: @tmlmobilidade/utils has prototype pollution in its setValueAtPath
IDs: CVE-2026-45325, GHSA-cmxg-94mg-jq94
Record: https://patchnext.com/advisories/cve-2026-45325 (revision 1, source checked 6 Nov 2026, 06:00 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.2)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: @tmlmobilidade/utils 20260509.340.15. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm @tmlmobilidade/utils: affected < 20260509.340.15; fixed in 20260509.340.15

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

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on @tmlmobilidade/utils.
- 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.

## Sources
- Verified: https://osv.dev/vulnerability/GHSA-cmxg-94mg-jq94 (OSV record GHSA-cmxg-94mg-jq94 lists affected ranges: npm @tmlmobilidade/utils >=0 <20260509.340.15 (fixed))
