fix(code-server): harden worker tokens, model proxy, publish, and Docker access - #138
Fixes the highest-priority findings from the code-server review:
Token expiry: worker tokens are an idle timeout now. Each successful use extends the expiry, so a long task keeps model access. Revoke on complete or cancel still ends access at once.
Model proxy: only POST model-call paths are forwarded, per provider. Other upstream paths return 404.
Bash allow list: removed find, python3, and npm run, which run arbitrary code behind a prefix match. Build and test tools stay. The docs state that the container and internal network are the real boundary.
complete_task: refuses tasks that are already completed, failed, or stopped.
Publish: one publish per task at a time (409 while one is in flight). The published state is re-checked under that slot. Protected paths match case-insensitively at any depth and include CODEOWNERS and .gitmodules. base_ref and branch must be valid ref names.
Local repos: a path on the server's host is refused unless FRONTAL_CODE_SERVER_ALLOW_LOCAL_REPOS=1. The worker e2e scripts set it.
Docker socket: code-server no longer mounts the raw socket. A pinned docker-socket-proxy on an internal network sits in front of it, and DOCKER_HOST points at it.
Docs: the worker security section matches the code. The README default permission is now prompt.
Verification
cargo fmt --check, cargo clippy -D warnings, and cargo test -p code-server pass with the dev Postgres and ClickHouse (128 unit tests plus integration suites).
New tests cover sliding token expiry (against Postgres), the proxy path allowlist, the bash allow list, a refused second completion, protected-path cases, and ref-name validation.
The docker socket proxy was tested against the local Docker daemon: network create and container run work, while exec, volume, and info calls are refused.
Ollama worker end-to-end (scripts/worker-e2e.sh, qwen2.5:1.5b): 2 of 2 tasks completed and published branches.
…ker access
- Worker tokens slide: each successful use extends expiry by the TTL, so a
long-running task keeps model access. Revoke on complete or cancel still
ends access immediately.
- The model proxy forwards only POST model-call paths per provider
(chat/completions, responses, v1/messages, Azure deployment chat). Other
upstream paths are refused with 404.
- Worker bash allow list drops `find`, `python3`, and `npm run`, which run
arbitrary code behind a prefix match. The docs say the network, not the
allow list, is the real boundary.
- complete_task refuses tasks that already completed, failed, or stopped.
- Publish: one publish per task at a time (409 while one is in flight), with
the published state re-checked under that slot.
- Publish: protected paths match case-insensitively at any depth and include
CODEOWNERS and .gitmodules. base_ref and branch must be valid ref names.
- Local repository paths are refused unless FRONTAL_CODE_SERVER_ALLOW_LOCAL_REPOS=1.
The worker e2e scripts set it.
- Docker: code-server no longer mounts the raw Docker socket. A pinned
docker-socket-proxy (CONTAINERS, IMAGES, NETWORKS, POST, PING, VERSION) on
an internal network sits in front of it, and DOCKER_HOST points at it.
- Docs: worker security section matches the code (workspace-write default,
tokens in Postgres, proxy path limits, idle-timeout expiry). README default
permission corrected to prompt.
Co-Authored-By: Claude Haiku 5.5 <noreply@anthropic.com>
The server now validates repository locations, Git refs, and publication requests. Worker access rules restrict commands and model-proxy paths, while valid token use refreshes token expiry. Docker worker mode routes API access through a socket proxy.
Changes: Worker and repository safeguards
Layer / File(s)
Summary
Repository and publication checks crates/code-server/src/lib.rs, crates/code-server/src/publish.rs, docs/CONTAINERS.md, scripts/*worker-e2e.sh
Task creation and publishing validate repository locations and refs. Publishing is serialized per task, protected patch paths are rejected, and completed, failed, or stopped tasks cannot be completed again.
Token validation receives a TTL and extends expiry for a matching, unrevoked, unexpired token. The worker access call and lifecycle documentation use the sliding-expiry behavior.
Worker command and model-proxy controls crates/code-server/src/worker_access.rs, README.md, docs/CONTAINERS.md
The shell allow-list removes find, python3, and npm run. The model proxy permits only recognized POST model-call paths. The README and container documentation describe worker permission defaults and access boundaries.
Docker API socket proxy infrastructure/compose/docker-compose.docker-worker.yml, infrastructure/README.md
Compose routes code-server Docker API calls through a digest-pinned proxy on an internal network. The raw Docker socket is mounted only into the proxy.
This change is meant to harden worker tokens, publishing and Docker access, but several of those protections can still be bypassed. A task can use file:// URLs to reach local repositories. A crafted patch can modify protected workflow files. A crafted Azure proxy path can reach non-model endpoints with the server's key. Fix these before merging.

Validate paths in headerless patches.
A worker can send a unified diff without a diff --git header. validate_patch skips its paths, but Git can apply it and publish a protected file to the task branch. Validate the paths Git applies, including rename sources and quoted paths.

Update completion status without replacing the context
If an in-flight publish records its result while complete_task awaits token revocation, completion can overwrite the published branch and commit with its stale context. Task snapshots then lose the publication result, and a later publish can bypass the published check.
Apply worker_status to the stored context under the context lock and use the updated context for the completion event. The same atomic field-update helper used for the publish-side merge can handle both writes.

validate_ref_name misses several refs that git rejects.
The check allows names such as a/.b, a., @, a/b.lock/c, and .hidden. Git refuses these, so the failure appears later as an opaque git error. This is not a security issue because option-like names are blocked. Add checks for components that start with . or end with .lock, a trailing ., and the name @.

Reduce timing sensitivity of the sliding-expiry test.
The test sleeps 1.2 s against a 2 s TTL. A slow CI host can pass the 2 s mark before the refresh call, and the test then fails. It also adds about 2.4 s of runtime. Use a longer TTL margin, or run the first sleep closer to half the TTL.

Document or bound the lost-token race in sliding validate.
validate now writes on every call. Postgres serializes concurrent updates to the same row, so no correctness defect results. Every model-proxy request now costs a row write, which adds WAL volume and row-lock contention for chatty workers. The single store thread already serializes all commands. If the write cost becomes measurable, update expires_at only when the remaining time is below about half of the TTL.
Add AND expires_at < now() + make_interval(secs => $2 / 2) as a possible refresh condition. This applies only to the refresh path, so you must split the query into a select and a conditional update.

Update the threat-model row to match the idle-timeout semantics.
Lines 49-50 now describe an idle timeout. The threat-model row at Line 106 still says "Revoked on completion, cancel, and expiry". The new text states that expiry is not a revocation. Reword the row, for example: "Revoked on completion and cancel. Expires after idle TTL."
The permission-mode section (Line 86) and Resolved item 1 (Line 113) also still list npm test and cargo as shell examples. This matches the code. They do not mention that find, python3, and npm run were removed. Optionally note that the allow list is not a sandbox.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Restrict container creation before treating the proxy as a security boundary.
If an attacker controls a process in code-server, CONTAINERS=1 and POST=1 permit POST /containers/create. The request can create a privileged container with a writable host bind mount. Mounting the socket :ro does not restrict that Docker API operation. The pinned proxy also permits POST /containers/{id}/exec through the CONTAINERS rule, even when EXEC is disabled. Use an authorization layer that checks the required operations and container-create parameters; API-section flags alone do not provide that restriction. (raw.githubusercontent.com)

A token that is stolen from the container is useful only for model calls and for its own task's endpoints. It stops working when the task completes or is cancelled, or when the server restarts (tokens are held in memory).
A token that is stolen from the container is useful only for model calls and for its own task's endpoints. The proxy forwards only model-call paths (for example `chat/completions`, `responses`, and `v1/messages`) and only `POST`, so a token cannot reach file, fine-tuning, or account endpoints. Tokens are stored as SHA-256 hashes in Postgres, so they survive a server restart. Each successful use extends the token's expiry by the configured TTL (`FRONTAL_CODE_WORKER_TOKEN_TTL_SECS`, default 7200), so the TTL is an idle timeout and a long-running task keeps access. The token is revoked as soon as the task completes or is cancelled.
If Postgres is unavailable, revocation logs the error and the task can still finish. Validation fails while Postgres is down. If Postgres recovers before the token expires, the token can authenticate and extend its expiry.
Fail closed or retry revocation while blocking access until it succeeds. Correct the documentation to match the resulting guarantee.
