## What is CVE-2026-27693?

CVE-2026-27693 is a medium-severity vulnerability in traccar, published on 5 May 2026. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.

### Official description

Traccar is an open source GPS tracking system. In org.traccar:traccar versions starting at 6.11.1 before 6.13.0, the KML and GPX export functionality writes device names to XML output without proper escaping. An attacker with low privileges can create a device with a crafted name that injects XML content into exported files. If another user exports and opens the affected KML or GPX file, this can corrupt the file structure and spoof exported location data. This issue is fixed in version 6.13.0.

Weakness: CWE-91 (XML Injection)

What it is: CVE-2026-27693 is a medium-severity vulnerability in traccar, published on 5 May 2026. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-27693 exists.

Affected product: traccar. No package-level version data is available, so check the vendor advisory linked from the reference page.

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.
