## What is CVE-2026-58115?

CVE-2026-58115 is a critical missing authorization vulnerability in Siemens SIMATIC IoT2050 Advanced, published on 11 Aug 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 SIMATIC IoT2050 Advanced (6ES7647-0BA00-1YA2) (All versions < V4.3.4.1 running Industrial OS with Node-RED installed). Affected devices do not enforce authentication on the Node-RED HTTP interface, allowing unauthenticated access to programming nodes that are capable of executing system commands on the server.
This could allow an unauthenticated remote attacker to create malicious flows through the HTTP interface in order to execute arbitrary code on the underlying server with maximum privileges.

Weakness: CWE-306 (Missing Authentication for Critical Functionality)

What it is: CVE-2026-58115 is a critical missing authorization vulnerability in Siemens SIMATIC IoT2050 Advanced, published on 11 Aug 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-2026-58115 in the wild and no public exploit code.

Affected product: Siemens SIMATIC IoT2050 Advanced. 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.
