Description

Nx is a monorepo solution for TypeScript and polyglot codebases. From 21.4.0 until 22.7.8 and from 23.0.0 until 23.1.1, the @nx/docker release pipeline builds docker tag, image lookup, and docker push invocations as shell command strings. The release.docker.repositoryName and registryUrl configuration values are interpolated into those strings and passed to /bin/sh -c, allowing shell syntax in untrusted Nx configuration to execute during nx release version or nx release publish. A pull request or repository configuration change can therefore execute commands with the release job's privileges and expose registry credentials or cloud tokens, and dry-run publishing does not prevent the vulnerable pre-check command from executing. This issue is fixed in versions 22.7.8 and 23.1.1.

• CWE-78Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.
