• CVE-2026-54546: 0.37% estimated exploitation activity in the next 30 days; percentile 31.21 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary PUT /api/basemap (the basemap import endpoint) fetches an attacker-supplied URL server-side with no SSRF protection whatsoever. Any authenticated user can submit a JSON body { "type": "...", "url": "<attacker url" }; the server calls fetch(url) against that URL and then reflects the response body (name, attribution, tiles[0], zoom levels) back to the caller in the OptionalTileJSON response. Because there is no IP-address classification, internal-only services are reachable: cloud metadata (http://169.254.169.254/...), loopback (http://127.0.0.1/...), RFC1918 ranges, and CGNAT. The response body flows back to the attacker, making this a full-read SSRF (not blind): the attacker reads the internal HTTP response verbatim. This enables theft of cloud instance credentials, internal service enumeration, and reading of internal-only HTTP endpoints from the network position of the CloudTAK API server. The only URL check in the basemap protocol layer (BasemapProtocol.isValidURL,…

# Patch Next advisory brief: CVE-2026-54546

Advisory: TAK-PS-Stats Web UI: Authenticated full-read SSRF in CloudTAK basemap import (PUT /api/basemap) — no IP-classification guard
IDs: CVE-2026-54546, GHSA-vqrw-qphh-p34v
Record: https://patchnext.com/advisories/cve-2026-54546 (revision 2, source checked 26 Oct 2026, 13:02 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.0)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: @tak-ps/cloudtak 13.22.1. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm @tak-ps/cloudtak: affected < 13.22.1; fixed in 13.22.1

## Suggested inspection (read-only)
- `npm ls @tak-ps/cloudtak --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 @tak-ps/cloudtak.
- 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://github.com/advisories/GHSA-vqrw-qphh-p34v (GitHub-reviewed advisory GHSA-vqrw-qphh-p34v lists affected ranges: npm @tak-ps/cloudtak >=0 <13.22.1)
