## What is CVE-2026-67367?

CVE-2026-67367 is a critical path traversal vulnerability in Siemens SIMOVE Fleetmanager V3.1, published on 8 Sep 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

A vulnerability has been identified in SIMOVE Fleetmanager V3.1 (All versions < V3.1.13), SIMOVE Fleetmanager V3.2 (All versions < V3.2.4), SIMOVE Fleetmanager V3.3 (All versions < V3.3.2), SIMOVE Fleetmanager V4.0 (All versions < V4.0.1), SIPLANT V1.7 (All versions), SIPLANT V2.2 (All versions), SIPLANT V3.0 (All versions), SIPLANT V3.1 (All versions < V3.1.4). Affected devices do not properly validate and neutralize directory traversal sequences in the file-serving endpoint of the embedded HTTP server. This could allow an unauthenticated remote attacker to read arbitrary files from the underlying operating system without any credentials, potentially exposing sensitive data such as credential stores, private keys, and configuration secrets.

Weakness: CWE-23 (Relative Path Traversal)

Check this codebase for CVE-2026-67367 and fix it if it is affected.

What it is: CVE-2026-67367 is a critical path traversal vulnerability in Siemens SIMOVE Fleetmanager V3.1, published on 8 Sep 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-67367 in the wild and no public exploit code.

Affected product: Siemens SIMOVE Fleetmanager V3.1. 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.
