## What is CVE-2025-68134?

CVE-2025-68134 is a high-severity denial of service vulnerability in everest-core, published on 21 Jan 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

EVerest is an EV charging software stack. Prior to version 2025.10.0, the use of the `assert` function to handle errors frequently causes the module to crash. This is particularly critical because the manager shuts down all other modules and exits when any one of them terminates, leading to a denial of service. In a context where a manager handles multiple EVSE, this would also impact other users. Version 2025.10.0 fixes the issue.

Weakness: CWE-20 (Improper Input Validation)

Check this codebase for CVE-2025-68134 and fix it if it is affected.

What it is: CVE-2025-68134 is a high-severity denial of service vulnerability in everest-core, published on 21 Jan 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-68134 exists.

Affected product: everest-core. 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.
