CVE-2026-104859: @nx/docker: OS command injection in the @nx/docker release pipeline

## Summary The `@nx/docker` release pipeline builds its `docker` invocations as shell command strings, interpolating `release.docker.repositoryName` and `registryUrl` from Nx configuration into them. Because those strings are handed to `/bin/sh -c`, a crafted repository or registry name executes as a command during `nx release version` and `nx release publish`. Anyone running a Docker release against a repository whose Nx configuration they do not control — or whose configuration a pull request has changed — executes the injected command with the privileges of the release job, which in CI typically holds registry credentials and cloud tokens. ## Severity Exploitable when someone runs a Docker release against attacker-supplied configuration, with high impact because release jobs hold publishing credentials. There is no known evidence of exploitation in the wild. ## Affected & Patched Versions | Package | Vulnerable | Patched | | --- | --- | --- | | `@nx/docker` | `>= 21.4.0, < 22.7.8`; `>= 23.0.0, < 23.1.1` | `22.7.8`, `23.1.1` | Every published `@nx/docker` release before the patched versions is affected. > [!IMPORTANT] > `--dry-run` does not protect you: one of the injected commands runs before the dry-run check, so even a dry-run publish reaches a shell. ## Remediation Upgrade to **22.7.8** (22.x line) or **23.1.1** (23.x line) or later: ``` nx migrate 23.1.1 ``` The fix is a drop-in and requires no configuration change. If you have run `nx release version` with a configuration you do not trust, delete the generated Docker version file before your next publish, since the composed reference is read back from disk. ## Details Several `docker` commands in the release pipeline (`docker tag` during `nx release version`; the image existence check and `docker push` during `nx release publish`) are built as shell command strings with the image reference interpolated in. The reference is composed from the project's `release.docker` `repositoryName` and `registryUrl`, so a value containing shell syntax is executed rather than passed to `docker`. ## Credits - **Arkadiusz Marta** (RE:SOURCE) — Reporter
