Applied at StartHLSSession and at the /hls URL handler; invalid IDs share the 404 of unknown sessions so the accepted format isn't enumerable. - /health no longer leaks the active filename, taskID prefix or client IP to non-loopback callers. Uses net.IP.IsLoopback so IPv4-mapped IPv6 (::ffff:127.0.0.1) is recognised and the empty-string parse failure stops bypassing the boundary. - unrar/7z passwords now travel through stdin instead of -p in argv, removing /proc//cmdline disclosure. Control characters in the password are rejected up front so a hostile NZB cannot feed extra prompt answers.

Three independent hardenings against the unauthenticated daemon surface, the long-lived agent SSE stream and the self-update channel. UPnP is now opt-in. The stream port + /hls endpoints have no auth, so publishing them on the WAN via the gateway was a default that exposed active downloads to anyone scanning the operator's external IP. New config downloads.enable_upnp (default false) gates the mapping; LAN and Tailscale clients continue to work unchanged. A startup log makes the new default visible. The agent SSE reader now uses a bounded bufio.Scanner instead of an unbounded ReadString. A hostile or buggy server can no longer grow daemon memory by streaming a single line forever or by emitting unbounded data: continuation lines — both are capped at 256 KiB and 1 MiB respectively, and an error is surfaced so SignalLoop reconnects. Self-update now verifies an ed25519 signature over checksums.txt when the binary was built with a release public key embedded (injected via goreleaser ldflags from RELEASE_SIGNING_PUBKEY). The companion scripts/sign-checksums runs in the release workflow when both the public-key variable and the private-key secret are present, uploading checksums.txt.sig next to the existing checksums file. Builds without the embedded key continue to update with SHA256-only verification; a --allow-unsigned flag is provided so users on a signed build can still install pre-signing releases or recover from an accidental unsigned release. A new scripts/gen-release-key helper documents the one-time keypair generation procedure required before flipping signing on. --- .github/workflows/release.yml | 22 ++++ .goreleaser.yml | 4 + internal/agent/signal_client.go | 47 ++++++--- internal/agent/signal_client_test.go | 43 ++++++++ internal/cmd/daemon.go | 1 + internal/cmd/self_update.go | 10 +- internal/cmd/upgrade.go | 7 +- internal/config/config.go | 1 + internal/engine/stream_server.go | 28 +++++- internal/engine/stream_server_test.go | 6 +- internal/engine/watch_reporter_test.go | 3 +- internal/upgrade/download.go | 36 ++++++- internal/upgrade/signature.go | 112 +++++++++++++++++++++ internal/upgrade/signature_test.go | 134 +++++++++++++++++++++++++ internal/upgrade/upgrade.go | 32 +++++- scripts/gen-release-key/main.go | 37 +++++++ scripts/sign-checksums/main.go | 60 +++++++++++ 17 files changed, 551 insertions(+), 32 deletions(-) create mode 100644 internal/upgrade/signature.go create mode 100644 internal/upgrade/signature_test.go create mode 100644 scripts/gen-release-key/main.go create mode 100644 scripts/sign-checksums/main.go diff --git a/.github/workflows/release.yml b/.github/workflows/release.yml index 8283150..ea07be7 100644 --- a/.github/workflows/release.yml +++ b/.github/workflows/release.yml @@ -27,6 +27,28 @@ jobs: env: GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }} SENTRY_DSN: ${{ secrets.SENTRY_DSN }} + # Empty when RELEASE_SIGNING_PUBKEY variable is unset — goreleaser + # accepts it and the resulting binary disables signature checks + # (back-compat: pre-signing releases continue to update).

Medium and low-severity hardenings plus a deferred-work plan for the cross-repo stream-token rollout. Stream server CORS: replace the wildcard Access-Control-Allow-Origin with an allowlist that echoes back only torrentclaw.com, app.torrentclaw.com, the local Next dev port (3030 — matches the web repo package.json) and any extras the operator adds via the new downloads.cors_extra_origins TOML key. A Vary: Origin header is now emitted whenever the request carries an Origin header so an intermediate cache cannot serve a stale ACAO to a different origin. URL scheme guard: openBrowser and OpenPlayer refuse any URL that is not http(s). Combined with passing the URL after "--" wherever the launched helper supports it (open, mpv, vlc, cvlc), this stops a leading "-" from being parsed as a switch by the spawned process. State file permissions: WriteState now writes 0o600 so the agent ID, PID and counters cannot be enumerated by another local user on a shared host. Matches the existing config file mode. ZIP slip defense-in-depth: extractZip extracts the safety check into safeZipPath, which canonicalises the entry name (normalising backslashes to "/"), rejects "..", "../" prefix and "/../" interior components, and verifies the final destination stays inside destDir before opening any file. Mirror fallback: documented the design for multi-provider mirrors.json hosting in the comment block on DefaultStaticFallbackURLs and added a follow-up note about signing it with the same ed25519 release key. The list is kept at one provider until the second host is provisioned and added to torrentclaw-web's STATIC_FALLBACKS. Deferred work: a new plan document Docs/plans/security-stream-token.md covers the per-task stream token (Phase 2.2 of the original audit) which requires coordinated web + CLI work and ships separately. --- Docs/plans/security-stream-token.md | 131 ++++++++++++++++++++++++++ internal/agent/mirror_client.go | 12 ++- internal/agent/state.go | 8 +- internal/cmd/daemon.go | 1 + internal/cmd/helpers.go | 17 +++- internal/cmd/helpers_test.go | 26 +++++ internal/config/config.go | 1 + internal/engine/stream_player.go | 28 +++++- internal/engine/stream_server.go | 90 ++++++++++++------ internal/engine/stream_server_test.go | 65 +++++++++++++ internal/engine/validate.go | 36 +++++++ internal/upgrade/extract.go | 58 ++++++++++-- internal/upgrade/upgrade_test.go | 37 ++++++++ 13 files changed, 462 insertions(+), 48 deletions(-) create mode 100644 Docs/plans/security-stream-token.md diff --git a/Docs/plans/security-stream-token.md b/Docs/plans/security-stream-token.md new file mode 100644 index 0000000..1a08e21 --- /dev/null +++ b/Docs/plans/security-stream-token.md @@ -0,0 +1,131 @@ +# Phase 2.2 — Per-task stream token (deferred) + +Status: deferred.
