fix(check): reject non-SQL files by extension — unblock v0.9.6 release - #1131
Conversation
…gression The Verdaccio sanity suite's path-traversal security test (test/sanity/phases/security.sh:96-103, present + passing since PR #844 in June 2026) regressed on v0.9.6. Not the test's fault: the altimate- core 0.7.0 upgrade in #1090 introduced a `multi_statement` safety rule that echoes the offending statement text back in its error message. When `altimate check ../../../../etc/passwd` runs, the CLI reads the file, parses each line as SQL, fails, and the engine emits: ERROR ... [multi_statement]: Disallowed statement type: ROOT:X:0:0:ROOT:/ROOT:/BIN/BASH The sanity test greps case-insensitive for `root:x:0` — matches — fails the release workflow. No content actually shipped: publish + GitHub Release + Docker were all skipped when sanity failed. Fix: honor the "SQL file" claim in check.ts:479's own comment. The prior filter only checked existence — non-`.sql` files were parsed happily. Now rejects anything without a `.sql`/`.ddl` extension before it reaches the engine, so no content is parsed or echoed. Extracted the extension test as `isSqlFile()` in check-helpers so it can be unit-tested independently. Verification: - rebuilt the darwin-arm64 binary and re-ran the exact sanity reproduction locally: pre-fix leaked ROOT:X:0 line; post-fix skips with "Warning: not a SQL file (extension \"none\"), skipping: ..." - 82/82 tests in test/cli/check-e2e.test.ts pass (9 new isSqlFile cases + 73 pre-existing) - typecheck clean; marker guard clean Follow-ups (not in this PR): - The engine-side fix — altimate-core's multi_statement rule should use statement TYPE NAMES, not raw content — file with core team - Consider capping message length in check.ts finding-mappers as belt-and-braces against similar future engine-echo bugs Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Use the SQL predicate during default discovery.
When users omit positional files, Lines 463-465 only scan **/*.sql. The command therefore skips schema.ddl, QUERY.SQL, and SCHEMA.DDL before this filter runs. Make default discovery use the same case-insensitive .sql and .ddl contract as isSqlFile.

Fixed in 5224705479 — default discovery now scans both **/*.sql and **/*.ddl and dedupes. Case-only variants (.SQL, .DDL) deferred; the isSqlFile filter accepts positional args in any case.

@sahrizvi, the update includes lowercase .sql and .ddl files and removes duplicates.
The finding remains valid for default discovery of .SQL and .DDL files. isSqlFile cannot accept these files when Glob.scan("**/*.sql") and Glob.scan("**/*.ddl") do not discover them first.
Please include case-insensitive default discovery in this PR, or confirm that you want a follow-up issue for the deferred behavior.

@sahrizvi, acknowledged. The current PR can stay focused on the release blocker.
The finding remains open for the follow-up because default discovery still excludes .SQL and .DDL.

Fixed in 5224705479 — same fix as the sibling comment on check.ts: default discovery now includes both extensions.
…isFile check, handler test + close #1130 Round 2 on the release/v0.9.6 hotfix — addresses the 5 bot findings on PR #1131 and rolls in the follow-up filed as issue #1130. - coderabbit MAJOR + cubic P2 (default-discovery gap): `**/*.sql` glob at check.ts:462 missed `.ddl` files that the new SQL_EXTENSIONS filter accepts. Now scans both extensions and dedupes. - cubic P2 (bare-extension dotfile): `isSqlFile` accepted files named literally `.sql` and `.ddl` as if the leading dot were an extension separator. Node's `path.extname` treats those as dotfiles with NO extension. Fixed to match: bare-`.sql`/`.ddl` filenames are rejected. - cubic P2 (directory with .sql suffix): a directory named `foo.sql` passed the extension filter. Added a `statSync(f).isFile()` gate that rejects directories (and symlinks-to-directories, since statSync follows symlinks) with a clear warning. - cubic P2 (test coverage gap): the `isSqlFile` tests only exercised the pure helper; if the CLI handler stopped calling the filter the tests would still pass. Added a handler-level integration test with mixed SQL/non-SQL input that asserts the warning is printed and no content leaks. Also added handler tests for the directory + bare dotfile cases. Updated the pre-existing "handles directory with .sql extension" test to match the new isFile behavior (was expecting "Error reading" from the downstream readFile crash). - #1130 follow-up (drop env-var mutation from dispatcher test files): removed the `beforeAll`/`afterAll` that mutated `process.env.ALTIMATE_TELEMETRY_DISABLED` in `test/altimate/dispatcher.test.ts` and `test/skill/release-v0.9.6-adversarial.test.ts`. Dispatcher.call already wraps every Telemetry.track in try/catch that swallows errors — the env-var was defensive against nothing and wasn't parallel-safe. Closes #1130. Verification: - 101/101 tests in check-e2e + dispatcher + release-adversarial pass - rebuilt darwin-arm64 binary; sanity reproduction still shows no leak - typecheck clean; marker guard clean Closes #1130 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Round 3 on the release/v0.9.6 hotfix — addresses 3 new bot findings on PR #1131: - coderabbit MAJOR (real leak surface): the extension filter and statSync isFile check both see the SYMLINK target, not the link. So `ln -s /etc/passwd passwd.sql` sailed through — link's .sql extension passed, statSync followed the link, /etc/passwd IS a regular file, readFileSync then read its content, and the safety renderer echoed the first line. Exact leak class this PR exists to close. Fix: `lstatSync` to detect symlinks; when one is present, `realpathSync` to resolve the target and require ITS extension to also be SQL. Preserves `link.sql -> real.sql` (both SQL); rejects `passwd.sql -> /etc/passwd`. Two new handler-level regression tests: • "handler rejects symlink whose target is NOT a SQL file" • "handler ACCEPTS symlink whose target IS a SQL file" Reproduced the attack locally with the built binary: pre-fix leaked the file's first line; post-fix skips cleanly. - coderabbit MAJOR (spy hygiene in check-e2e.test.ts): the spyOn calls on process.stdout.write / process.stderr.write / console.error in beforeEach were never restored. Bun doesn't auto-restore spyOn across test files. Added `mock.restore()` in afterEach. - coderabbit MAJOR (dispatcher singleton isolation): same class of finding as the env-var one — the tests mutate module-wide `nativeHandlers`/`_ensureRegistered`. Not fixable without an instance-per-test refactor of the whole Dispatcher module. Documented the concurrency contract in-file: safe under bun's default sequential test-file execution; #1130 already tracks the broader parallel-safety cleanup this class of finding calls for. Same disposition as the release-adversarial file. Verification: - 103/103 tests pass (2 new symlink cases) - rebuilt darwin-arm64 binary; symlink attack repro shows the warning and no content leak - typecheck clean; marker guard clean Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

coderabbit MAJOR on prior round: my "resolve symlink target + check extension" approach opened a TOCTOU race. Between validation (realpathSync + isSqlFile) and readFileSync(f), an attacker with write access to the parent directory can swap ``passwd.sql`` from pointing at ``real.sql`` to pointing at ``/etc/passwd``. The read then follows the new link and echoes the file's content — the exact leak class this PR closes. Closing the race properly requires open-once + fstat + read-from-fd plumbed through every caller — a big refactor for a CLI most invocations don't hit. Simpler + secure: refuse symlinks entirely. Users who need to check a linked file pass the resolved target directly. Reverses cubic's earlier "accept link-to-SQL" request. The tradeoff (lose the accept-link-to-SQL convenience) favors simplicity + security over convenience — noted in the coderabbit thread reply. Also updates the pre-existing "handles symlinked SQL files" test to match the new rejection behavior. 103/103 tests pass; typecheck + marker guard clean.

Approving — unblocks the v0.9.6 release cleanly and fixes the real bug rather than the test.
Reviewed: the extension filter now honors its own comment (isSqlFile with correct dotfile/path.extname edge semantics, unit-tested including the exact sanity-test path), symlinks are rejected TOCTOU-safe with lstat failing closed, and the no-args glob gains .ddl consistently. Verification is convincing: pre/post binary reproduction of the sanity leak plus 82/82 e2e tests. The two follow-ups (engine-side multi_statement message echoing raw content; message-length caps across finding mappers) are the right scope cuts — the engine one is the true root cause and worth filing promptly.
Note: "Kilo Code Review" failure is again its API rate-limit non-run, not a finding; all substantive CI is green.

Acknowledged and deferred. The blanket symlink rejection at c65af81e closes the "user passes a symlink" attack. The residual "attacker races the parent dir between validate and readFileSync" leak requires open-once + fstat + read-from-fd threaded through every check-runner — a real refactor that this release-blocker hotfix can't carry. Realistic threat model: attacker needs write access to the same directory + microsecond race window + prior knowledge of the invocation. Filing a follow-up issue to properly close the residual race across the read path.

root:x:0in the output. Historically that output wasWarning: file not found, skipping: /...(on macOS) orNo SQL files found(on Linux) — no leak.v0.9.6 shipped the
altimate-core0.5.1 → 0.7.0 upgrade in #1090. One of its new safety rules —multi_statement— echoes the offending statement text back inside its error message. When the CLI reads/etc/passwdon Linux CI, parses each line as SQL, and fails, the engine emits:The sanity grep matches → test fails → publish skipped. Not the test's fault; the engine change regressed it. No customer would have seen this in practice (they're unlikely to
altimate check /etc/passwd), but the sanity net catches the class of "CLI leaks file content to stdout" cleanly and it's right to fail-closed here.The fix
The prior file filter at
packages/opencode/src/cli/cmd/check.tshad a comment that said "Filter to only existing .sql files" — but the code only checked existence, not extension. That was the actual bug:altimate check /etc/passwdwas accepted, parsed, and echoed. This PR makes the filter honor its own comment:isSqlFile()accepts.sql/.ddl(case-insensitive) — extracted tocheck-helpers.tsso it's unit-testable independently.Non-SQL content no longer reaches the engine at all — no parse, no error message, no leak. The sanity test now passes because the CLI output for
altimate check ../../../../etc/passwdbecomes:Verification
ROOT:X:0:..., post-fix skips cleanly with the warning above.test/cli/check-e2e.test.tspass — 9 newisSqlFilecases (accept .sql/.ddl in both cases; reject the exact sanity-test path, extensionless files, unrelated extensions, dotfiles, directory paths, dot-in-dir paths) + 73 pre-existing.bun turbo typecheckclean.Marker Guard(strict, vsorigin/main) clean.Follow-ups (not in this PR)

Blocks non-SQL, non-regular, and all symlinked files in
altimate checkto prevent parsing arbitrary content and leaking it via engine errors. Previously any existing path was parsed; now only regular.sql/.ddlfiles are processed, and symlinks are rejected to close a TOCTOU race..sql/.ddl; rejects bare.sql/.ddldotfiles, directories or symlinks, and any non-SQL paths. Non-SQL paths warn and are skipped; if none remain, prints “No SQL files found to check.” Default discovery now scans**/*.{sql,ddl}.isSqlFile()andSQL_EXTENSIONSinpackages/opencode/src/cli/cmd/check-helpers.ts.
