From 4.0.0 until 4.3.2, the stable publish workflow interpolates steps.release.outputs.body directly into an echo command in Bash source before writing RAW_RELEASE.md. Contributor-controlled shell metacharacters in generated release-note text can therefore execute when a maintainer starts a stable release, allowing modification of generated artifacts or workspace scripts and affecting later release steps that hold GITHUB_TOKEN and write permissions.
