fix(symphony): close three path traversal issues at the IPC boundary - #1384
Conversation
- reject contribution IDs that are not a single path segment before they are joined into the Symphony directory in startContribution and createDraftPR - reduce external document names to a bare file name before joining them onto the documents cache, so traversal is neutralised without refusing real link text like "docs/architecture.md" - confirm a stored localPath is this contribution's clone before symphony:cancel removes it recursively, since a user may legitimately pick any working directory - cover all three, with a positive control for the generated ID formats and a guard test that cancel skips deletion for a non-clone path

Greptile SummaryThe PR decomposes the Symphony IPC handler and adds path-safety checks for contribution IDs, document names, and recursive cancellation cleanup. Two safety gaps remain:
Confidence Score: 2/5The PR should not merge until recursive cleanup verifies clone identity precisely and document flattening handles basename collisions without dropping content. The cancellation guard can authorize recursive deletion of an unrelated Git checkout, and distinct valid documents can be flattened onto one destination and silently overwrite each other. Files Needing Attention: src/main/ipc/handlers/symphony/shared.ts, src/main/ipc/handlers/symphony/lifecycle.ts, src/main/services/symphony-runner.ts
|
| Filename | Overview |
|---|---|
| src/main/ipc/handlers/symphony/shared.ts | Adds shared validation and clone-provenance helpers, but the origin substring comparison can authorize deletion of an unrelated checkout. |
| src/main/ipc/handlers/symphony/lifecycle.ts | Adds guarded cancellation cleanup, although its destructive operation relies on the insufficient clone-identity predicate. |
| src/main/services/symphony-runner.ts | Safely flattens path-like document names but can overwrite distinct documents that share a basename. |
| src/main/ipc/handlers/symphony/contributionStart.ts | Applies contribution-ID validation before constructing contribution paths and integrates the shared document-name sanitizer. |
| src/main/ipc/handlers/symphony/contributionFinish.ts | Validates contribution IDs before resolving metadata paths in the draft-PR flow. |
| src/main/ipc/handlers/symphony/index.ts | Preserves the prior public registration interface while composing the decomposed Symphony handler modules. |
| src/tests/main/ipc/handlers/symphony.test.ts | Adds cancellation cleanup coverage but does not exercise false-positive origin matches. |
| src/tests/integration/symphony.integration.test.ts | Adds traversal and valid-input coverage but does not test basename collisions between distinct documents. |

When a user-selected localPath points to another Git clone whose origin merely contains the expected repository basename, isContributionClone returns true and cancellation recursively deletes that unrelated working tree and its uncommitted files. How this was verified: The cleanup path relies only on the .git check and the unbounded origin.includes(repoName) comparison before calling recursive fs.rm.

When distinct valid references such as an external link named docs/architecture.md and an internal docs/architecture.md reach this loop, both names reduce to architecture.md; the later write silently overwrites the earlier document, leaving Auto Run with incomplete or incorrect source material.

src/main/ipc/handlers/symphony/contributionStart.ts lines 382-385, perform the
same validation and remove non-null assertions so ActiveContribution never
receives undefined. Alternatively enforce this validity in the shared
createDraftPR contract.
- Around line 246-253: Update the document-fetch logic in the contribution
finish and start handlers to use a shared timeout via AbortSignal.timeout and
enforce MAX_DOCUMENT_BYTES before allocation and during response.body
consumption. Replace post-read response.text/arrayBuffer handling with bounded

preserving existing HTTP error and success results.
- Around line 317-409: Introduce and use a shared serialized read-modify-write
helper for every Symphony state mutation in contributionFinish.ts,
contributionStart.ts, lifecycle.ts, and sync.ts. Move each read and mutation,
including contributionFinish.ts’s duplicate check and contributionStart.ts’s
post-operation updates, inside the serialized commit so state is re-read after
long-running operations and concurrent history, active-contribution, and
statistics updates cannot overwrite one another.

search qualifiers.
In `@src/main/ipc/handlers/symphony/lifecycle.ts`:
- Around line 165-204: Serialize all Symphony state read-modify-write operations
by adding a shared single-writer helper in shared.ts, such as withState, that
queues mutations, reads fresh state, executes the callback, and writes it before
releasing the queue. Route registerActive, updateStatus, complete, and cancel
through this helper while preserving each handler’s existing mutation and return
behavior.
In `@src/main/ipc/handlers/symphony/shared.ts`:
- Around line 169-188: Add a locked mutateState operation around readState,
mutation, and write persistence so concurrent IPC handlers cannot overwrite each
other’s updates; update every state-mutating handler, including
symphony:registerActive and symphony:updateStatus, to use it. Make the final
write atomic by persisting to a temporary file and replacing the state file only
after the complete contents are written.
- Line 155: Update the repository validation around the origin lookup to parse
standard URL and SCP-style Git remote formats, extract the final repository
segment, strip only an optional .git suffix, and require an exact match with
repoName instead of using includes(). Preserve cancellation cleanup only when
this exact repository-name check succeeds.
In `@src/main/ipc/handlers/symphony/sync.ts`:
- Line 106: Update checkPRStatuses to prevent concurrent state updates from
being overwritten during its awaited network requests: either re-read state
immediately before the final write and apply only its computed changes, or
serialize the entire mutation through the shared state-mutation mutex/queue in
shared.ts. Preserve the existing merged flags, PR information, and history moves
while avoiding replacement of unrelated updates.
- Around line 178-183: Validate contribution.id with validateContributionId
before each metadataPath path.join in sync.ts, and validate the
renderer-provided contributionId in registerActive before persisting it. Also
validate IDs loaded by readState before using them in filesystem paths,
rejecting invalid values rather than allowing path traversal.

without another handler overwriting concurrently persisted fields.
- Around line 376-388: Update the handler call site to pass the existing

Check the exit code of git rev-list.
Line 125 reads only stdout and falls back to 0. If rev-list fails, for example when baseBranch is not a resolvable local ref after fork setup renamed origin, stdout is empty and commitCount becomes 0. The handler then returns success: true with no PR fields, and the caller treats it as "no commits yet". The draft PR is never created, and no error reaches the user. Fail loudly on a non-zero exit code.

Both draft PR call sites trust an unparsed PR result. createDraftPR in src/main/ipc/handlers/symphony/shared.ts parses prNumber from a regex over gh pr create stdout and returns success: true even when the match fails, so prUrl and prNumber can be undefined. Both callers persist that result without checking it. Add the check at the shared contract, or check it at each caller.

Serialize Symphony state updates.
contributionStart.ts reads state before asynchronous clone, fork, and PR operations, then writes that stale snapshot. Concurrent updates can be overwritten, including history, active contributions, and cumulative statistics. The duplicate check in contributionFinish.ts is also not atomic.
Use a shared serialized read-modify-write helper for all Symphony state mutations in contributionFinish.ts, contributionStart.ts, lifecycle.ts, and sync.ts. Re-read state inside the serialized commit after long-running operations.

Serialize the read-modify-write of the Symphony state file.
Every handler in this file runs readState, mutates the returned object, then writeState. No lock guards this sequence. symphony:updateStatus fires often during Auto Run, while symphony:complete and symphony:cancel mutate the same file. If two handler invocations interleave, the second writeState overwrites the first mutation. A lost complete write drops a history entry and its statistics.
Add a single-writer queue or mutex in shared.ts, then route all state mutations through it. This applies to registerActive (Lines 165-204), updateStatus (Lines 246-261), complete (Lines 289-431), and cancel (Lines 456-487).

Serialize state mutations.
Handlers such as symphony:registerActive and symphony:updateStatus read a state snapshot, mutate it, and later write it back. Concurrent IPC requests can both read the same snapshot. The last write then discards the other request's update.
Add a locked mutateState() operation that performs read, mutation, and persistence as one critical section. Use it from all state-mutating handlers. Use atomic file replacement for the final persistence step.

checkPRStatuses can lose concurrent state updates.
The handler reads the full state at Line 106, performs many awaited network requests, and then writes the full state back at Line 328. Any other Symphony handler that updates state.json during that window is overwritten. The window is large here, because it spans one HTTP request per history entry and per active contribution with a PR.
Two mitigations are possible:
- Re-read the state right before writing and re-apply only the computed changes (merged flags, PR info, history moves).
- Serialize state mutations behind a shared mutex or queue in
shared.ts.
Also applies to: 247-328

The "where I diverged from the review suggestions" section is exactly the right way to handle bot feedback, and both of those calls are correct: containing I checked the two bot reviews against the code. Most of what CodeRabbit flagged as "Major" is pre-existing in Also, CodeRabbit's "critical" call on Two things in the genuinely new code before I'm happy, though: 1. Blocker: the origin match in

Reducing to the basename is the right call, but two distinct references such as One process note, not a code issue: this branch carries all of #1369, which is still open.

… document names - compare only the final segment of the origin with an optional .git suffix stripped, so an unrelated checkout whose URL merely contains the repository name can no longer authorise the recursive delete - fail closed when repoSlug carries no owner, instead of accepting the bare .git check alone - suffix a document whose file name is already taken in the batch rather than overwriting it, through one shared helper used by both document loops - cover the false-positive origins, the fork-rewritten origin, and collisions including case-insensitive and extensionless names
test(symphony): cover basename collisions through the document loop - drive startContribution with two references that reduce to the same file name and assert both are written to distinct destinations - the existing runner tests all pass an empty documentPaths, so this loop had no coverage
Thanks Pedram, both done. 1. Origin match. It now compares the final segment of the origin with the optional I ran the guard in the app against real checkouts with uncommitted files in them: the three decoy origins survive, and the three genuine ones (including a fork-rewritten origin) still get cleaned up. 2.
