Release notes

*Sourced from [anthropics/claude-code-action's releases](https://github.com/anthropics/claude-code-action/releases).*

> v1.0.77
> -------
>
> Subprocess environment scrubbing for untrusted-input workflows
> --------------------------------------------------------------
>
> Workflows that configure `allowed_non_write_users` now automatically get `CLAUDE_CODE_SUBPROCESS_ENV_SCRUB=1`, which makes Claude Code (v2.1.79+) strip Anthropic and cloud provider credentials from the environment of subprocesses it spawns (Bash tool, hooks, MCP stdio servers). The parent Claude process keeps these vars for its own API calls — only child subprocess environments are scrubbed.
>
> **Why:** Workflows that process untrusted input (issue triage, PR review from non-write users) are exposed to prompt injection. A malicious issue body could trick Claude into running a Bash command that reads `$ANTHROPIC_API_KEY` via shell expansion and leaks it through an observable side channel. Scrubbing the subprocess environment removes the read primitive entirely.
>
> **What's scrubbed:** Anthropic auth tokens, cloud provider credentials, GitHub Actions OIDC and runtime tokens, OTEL auth headers.
>
> **What's kept:** `GITHUB_TOKEN` / `GH_TOKEN` — so wrapper scripts can still call the GitHub API.
>
> **Opt out:** Set `CLAUDE_CODE_SUBPROCESS_ENV_SCRUB: "0"` at the job or step level if your workflow legitimately needs a subprocess to inherit these credentials.
>
> **No action required** for most users — if you've configured `allowed_non_write_users`, scrubbing is now on automatically. If your workflow breaks because a subprocess expected inherited credentials, re-inject them explicitly (e.g., via MCP server `env:` config) or use the opt-out.
>
> What's Changed
> --------------
>
> * Auto-set subprocess env scrub when allowed\_non\_write\_users is configured by [`@​OctavianGuzu`](https://github.com/OctavianGuzu) in [anthropics/claude-code-action#1093](https://redirect.github.com/anthropics/claude-code-action/pull/1093)
