## What is CVE-2026-54546?

CVE-2026-54546 is a medium-severity server-side request forgery vulnerability in dfpc-coe CloudTAK, published on 17 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

CloudTAK is a browser-based Common Operating Picture and situational awareness tool compatible with TAK. Prior to 13.22.1, the authenticated PUT /api/basemap endpoint passes an attacker-controlled URL through importBasemapURL() in api/routes/basemap.ts to fetch(url) without resolved-address classification or redirect revalidation. BasemapProtocol.isValidURL in api/lib/interface-basemap.ts checks only the HTTP or HTTPS scheme and is not applied on the vulnerable import path. Direct internal addresses, alternate IP encodings, and redirects to internal addresses can reach cloud metadata, loopback, private, and CGNAT HTTP services. The OptionalTileJSON response reflects fields including name, attribution, and tiles[0] to the caller, making the request forgery full-read rather than blind and enabling cloud credential theft and internal service disclosure. This issue is fixed in version 13.22.1.

Weakness: CWE-918 (Server-Side Request Forgery)

Check this codebase for CVE-2026-54546 and fix it if it is affected.

What it is: CVE-2026-54546 is a medium-severity server-side request forgery vulnerability in dfpc-coe CloudTAK, published on 17 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-54546 exists.

Affected packages and fixed versions:
- @tak-ps/cloudtak (npm): affected all versions; fixed in 13.22.1
- @tak-ps/cloudtak (npm): affected all versions; fixed in 13.22.1

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
