Motivation

  • Prevent an authorization bypass where API-key/session callers could supply arbitrary project_id and access other projects' Blob/KV data.
  • Ensure data-plane handlers enforce the same project-scoped boundaries and permission checks that management endpoints already require.

Description

  • Added permission_guard! checks to Blob data handlers (upload, delete, list, copy, head, download) to require BlobRead/BlobWrite/BlobDelete as appropriate.
  • Added permission_guard! checks to KV handlers (get, set, del, incr, expire, ttl, keys) to require KvRead/KvWrite/KvDelete as appropriate.
  • After extracting project_id, call project_scope_guard! to confine deployment-token auth to its bound project before performing storage operations, and updated imports to include project_scope_guard.
  • Recorded the security fix in CHANGELOG.md under ## [Unreleased].

Testing

  • Ran cargo check -p temps-blob --lib and it completed successfully.
  • Ran cargo check -p temps-kv --lib and it completed successfully.
  • Verified code formatting and static checks via repository checks (git diff --check) with no reported issues.

Runs cargo check + lib tests on the tempsdev1 self-hosted runner for
pushes to main/feature/**/fix/** and manual dispatch. Scoped to push
and workflow_dispatch only (never pull_request/pull_request_target) so
fork PRs can never execute on the self-hosted host. Uses a persistent,
isolated CARGO_TARGET_DIR outside the runner work dir so the build
cache survives checkout cleans and is reused across runs.

A warm CARGO_TARGET_DIR caches the example plugins' build-script fingerprint,
so after actions/checkout git-cleans the source tree the script is skipped and
include_dir!(".../web/dist") panics on the missing dir. Recreate the debug
placeholder assets up front so the check is independent of build-script cache.

temps-cli embeds crates/temps-cli/dist via include_dir!; like the example
plugins its build.rs placeholder is skipped on a warm cache, so generalize the
prep step to cover every include_dir! dist target, not just the plugins.

…vy crates

cargo test --lib --workspace pulled in temps-domains' real-Pebble ACME tests,
which need a challenge-responder network this box can't provide. Match the
unit-a/unit-b crate list from rust-tests.yml instead (Docker+networking-heavy
crates run in hosted's dedicated integration jobs, not here).

Its local_provider tests launch a real bundled Chromium against live
example.com/github.com. The hosted ubuntu-latest image ships
google-chrome system-wide so headless_chrome reuses it; this self-hosted
box has no system browser, so headless_chrome auto-downloads one and the
parallel tests race on the binary (Text file busy) and debug ports (no
available ports between 8000 and 9000). It is a live-network browser
integration test, not a unit test, and hosted CI already covers it.

The functional change was carried into upstream security-hardening PR gotempsh#676 and its merged replacement gotempsh#677. Upstream gotempsh#676 explicitly lists this fork PR in its source coverage.

Fork main has now been fast-forwarded to upstream main at 7250ab59b38d3138014ade7f5d6391c856eaa4f7. Closing this obsolete fork PR as part of the upstream synchronization; its branch history is retained.
