## What is CVE-2026-55061?

CVE-2026-55061 is a low-severity command injection vulnerability in uniget-org cli, published on 17 Sep 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.

### Official description

uniget is a universal installer and updater for (container) tools. Prior to 0.27.6, the hooks edit command in cmd/uniget/hooks.go parses UNIGET_EDITOR or EDITOR with strings.Split(editor, " ") and passes every space-delimited suffix as an argument to the selected editor executable. An attacker who can influence the editor environment and cause hook editing can supply unexpected editor arguments, potentially causing unintended actions with the privileges of the uniget process account. Go os/exec does not evaluate shell operators in these arguments, so the advisory's wrapper demonstration establishes argument delivery but does not establish shell command interpretation. This issue is fixed in version 0.27.6.

Weakness: CWE-88 (Improper Neutralization of Argument Delimiters in a Command)

What it is: CVE-2026-55061 is a low-severity command injection vulnerability in uniget-org cli, published on 17 Sep 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2026-55061 in the wild and no public exploit code.

Affected packages and fixed versions:
- gitlab.com/uniget-org/cli (Go): affected all versions; fixed in 0.27.6
- gitlab.com/uniget-org/cli (Go): affected all versions; fixed in 0.27.6
- gitlab.com/uniget-org/cli (Go): affected all versions; fixed in 0.27.6

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.
