Source description

As published by the source; long descriptions are shortened.

xapi-lib@88.2.3, 88.2.5, 90.2.1, and 90.3.1 describes itself as a package for getting IP location and metadata. Its preinstall hook runs `node index.js` on npm install and requests `https://realwbx.com/ip.php?ip=8.8.8.8` with the hardcoded Authorization value `fa79878bc2cfb48bd5127ae26fb661b1`, which is the same in all four versions and differs from the value in each of the account's other packages. The npm account conx3993 published xapi-lib on 2026-10-15, one of 9 packages from that account between 2026-09-30 and 2026-10-15 whose preinstall hook calls realwbx.com. --- _-= Per source details.

# Patch Next advisory brief: GHSA-wm6w-9vgq-gw26

Advisory: Malicious code in xapi-lib (npm)
IDs: GHSA-wm6w-9vgq-gw26
Record: https://patchnext.com/advisories/mal-2026-17896 (revision 1, source checked 4 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: Unrated
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 xapi-lib: affected every version

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