## What is CVE-2026-2248?

CVE-2026-2248 is a critical authentication bypass vulnerability in METIS WIC, published on 11 Feb 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

METIS WIC devices (versions <= oscore 2.1.234-r18) expose a web-based shell at the /console endpoint that does not require authentication. Accessing this endpoint allows a remote attacker to execute arbitrary operating system commands with root (UID 0) privileges. This results in full system compromise, allowing unauthorized access to modify system configuration, read sensitive data, or disrupt device operations

Weakness: CWE-306 (Missing Authentication for Critical Functionality), CWE-287 (Improper Authentication)

Check this codebase for CVE-2026-2248 and fix it if it is affected.

What it is: CVE-2026-2248 is a critical authentication bypass vulnerability in METIS WIC, published on 11 Feb 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-2026-2248 in the wild and no public exploit code.

Affected product: METIS WIC. 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.
