## What is CVE-2026-107202?

CVE-2026-107202 is a critical command injection vulnerability in jonssonyan h-ui, published on 7 Oct 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

A command injection vulnerability exists in the h-ui (version v0.0.25 and below) administrative API due to improper validation of the listen configuration field. When an authenticated administrator submits a value containing shell metacharacters, the application constructs nftables/iptables rule strings using fmt.Sprintf and executes them via bash -c as root. Because the listen field lacks port or format validation, arbitrary OS commands can be injected and executed with root privileges.

Weakness: CWE-77 (Improper Neutralization of Special Elements used in a Command)

Affected product: jonssonyan h-ui. 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.
