If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Suggestion: Using parseInt for ID parsing accepts malformed values like 1abc/1e2 and can coerce to unintended classroom IDs, causing incorrect data access. Use the shared strict classroom ID parser (positive safe integer validation) instead of permissive parsing. [incorrect variable usage]
Severity Level: Major ⚠️
- ⚠️ Malformed classroom IDs mapped to unintended classrooms.
- ⚠️ Filter endpoint inconsistent with strict ID parser.
- ⚠️ Potential data leakage across classrooms on user typos.Steps of Reproduction ✅
1. Inspect the shared classroom ID parser in `src/lib/auth/membership-guard.ts:75-86`:
`parseClassroomId(value)` only accepts numbers or strings matching `/^[1-9]\d*$/`, checks
`Number.isSafeInteger` and `classroomId > 0`, and throws `ApiError(400, "Invalid classroom
ID")` for malformed inputs like `"42abc"` or `"1e2"`, as verified by tests in
`src/__tests__/lib/membership-guard.test.ts:76-80`.
2. In the filter endpoint, `src/app/api/doubts/filter/route.ts:16-19` parses `classroomId`
with `const classroomIdInt = parseInt(classroomId);` and only rejects values where
`isNaN(classroomIdInt)`, meaning inputs such as `"42abc"` are coerced to `42` and `"1e2"`
to `1` instead of being rejected.
3. Start the app and issue `GET /api/doubts/filter?classroomId=42abc&subject=Math`; the
handler at `src/app/api/doubts/filter/route.ts:8-19` reads `classroomId` from
`searchParams`, computes `classroomIdInt = 42` via `parseInt`, and passes the `isNaN`
check (line 17) so no error response is returned.
4. At `src/app/api/doubts/filter/route.ts:21-23`, the `where` clause is built using
`eq(doubtsTable.classroomId, classroomIdInt)` and the subsequent query at 25-37 returns
doubts for classroom ID 42, even though the request supplied an invalid classroom
identifier according to the stricter `parseClassroomId` contract; similar malformed inputs
like `"1e2"` would be treated as classroom 1, potentially exposing data from the wrong
classroom.

Suggestion: The filter condition omits the soft-delete predicate, so records marked deleted are returned again through this endpoint. Include deletedAt is null in the where condition to match the rest of the doubts APIs. [logic error]
Severity Level: Major ⚠️
- ⚠️ Soft-deleted doubts reappear in filtered subject lists.
- ⚠️ Filter endpoint diverges from deletion semantics elsewhere.
- ⚠️ Users see doubts they previously deleted or removed.Steps of Reproduction ✅
1. A doubt is soft-deleted via the delete action handler in
`src/app/api/doubts/action/[id]/route.ts:262-287`, which loads the doubt with
`isNull(doubtsTable.deletedAt)` and then calls `db.update(doubtsTable).set({ deletedAt:
new Date() }).where(eq(doubtsTable.id, doubtId))` at line 287, setting `deletedAt` to a
non-null timestamp.
2. Normal listing endpoints consistently exclude such soft-deleted doubts:
`src/app/api/doubts/route.ts:66` initializes `conditions: SQL[] =
[isNull(doubtsTable.deletedAt)]`; `src/app/api/bookmarks/route.ts:29` applies
`and(inArray(doubtsTable.id, doubtIds), isNull(doubtsTable.deletedAt))`;
`src/app/api/classrooms/[id]/export/route.ts:39` includes `isNull(doubtsTable.deletedAt)`
in `conditions`; `src/app/api/replies/route.ts:43` and 149 both query doubts with
`and(eq(doubtsTable.id, doubtId), isNull(doubtsTable.deletedAt))`.
3. Call the new filter endpoint with `GET /api/doubts/filter?classroomId=<soft-deleted
doubt classroom>&subject=<subject>` so that the soft-deleted doubt matches the classroom
and subject.
4. In `src/app/api/doubts/filter/route.ts:21-23`, the `where` clause is built only on
`doubtsTable.classroomId` and `doubtsTable.subject` and the subsequent query at lines
25-37 `.from(doubtsTable).where(where)` lacks any `isNull(doubtsTable.deletedAt)`
predicate, causing the soft-deleted doubt (with non-null `deletedAt`) to be returned again
through this endpoint despite being hidden from other APIs.

- src/__tests__/lib/anonymity.test.ts had a stray extra '});' at line 60 that duplicate-closed the describe block, causing a syntax error that failed TypeScript Check, ESLint, and Unit Tests across the board - drizzle/0013_silky_gateway.sql is an orphan migration file not present in drizzle/meta/_journal.json; removing it resolves the Migration Check duplicate-prefix failure These are pre-existing repo-wide issues blocking CI on every PR.
- Remove duplicate closing brace in anonymity.test.ts breaking TS compilation
- Fix NODE_ENV/ANON_HANDLE_SALT mutation to use mutable env view consistently
- Convert route.test.ts from vitest to jest syntax (project uses jest, not vitest)
- Remove orphaned 0013_silky_gateway.sql migration not registered in journal.json
and duplicating tables already covered by 0014_practice_attempts.sql
- Fix sendDailyDigest test to invoke the Inngest handler via .fn() instead of
calling the InngestFunction wrapper object directly
- Fix mockSendDigestEmail to resolve {success:true} instead of undefined
- Align teacher-insights test error message expectations with actual API
response strings (Invalid classroom ID / Access denied to this classroom)
- Restore orgRoleEnum, organizationsTable, organizationMembershipsTable - Add organizationId column to classroomsTable with FK constraint - Re-enable multi-tenant organization feature that was removed in PR knoxiboy#731 - Consumers of these exports (organizations/route.ts, rooms/route.ts, analytics/route.ts) now compile without errors Fixes knoxiboy#777
…rations, tests)
This repo-wide CI is broken on main independent of this PR's schema restore,
so these fixes are required for any PR (including this one) to pass CI green.
TypeScript/Build (src/**):
- Fix ~50 implicit-any errors across API routes, inngest jobs, and lib helpers
by annotating map/filter/sort/reduce callbacks and transaction handlers with
their inferred element types.
- Fix profile/page.tsx null-safety on dbUser.karmaScore access.
- Fix db.test.ts readonly-property delete operator error.
Migrations (drizzle/):
- Remove two orphaned duplicate-prefix migration files (0008_audit_logs.sql,
0013_silky_gateway.sql) that were never registered in _journal.json --
leftovers from a prior merge conflict that left the drizzle snapshot chain
stuck at migration 0013.
- Regenerate the real outstanding diff (audit_logs, video_jobs) as
0017_wild_klaw.sql so now reports a clean, no-op
state matching schema.ts.
Tests (src/__tests__/):
- teacher-insights.test.ts: update stale error-message assertions to match
the route's actual (correct) 400/403 responses.
- digest-functions.test.ts: invoke the Inngest function's underlying .fn
handler instead of the wrapped Inngest SDK object, and fix the
sendDigestEmail mock to resolve {success: true} matching its real contract.
Verified locally: tsc --noEmit clean, eslint clean, npm run build succeeds,
211/211 tests pass across 41 suites, drizzle-kit generate reports no schema
changes.

Hi! Thank you for the PR. The logic looks good, but since we recently migrated the database pools and refactored our routes into clean services, there are active merge conflicts in your target files. Please pull the latest changes from main, resolve the conflicts, and update this PR so we can run the test builds. Thanks! |

Hey @knoxiboy! 👋 Ready for review on #743: Add subject-based doubt filtering with proper authorization (issue #733). The original endpoint had no auth, no membership checks, and leaked raw author emails — a security hole. This PR adds Suggested GSSoC labels (to help with contribution scoring):
Security fixes to public endpoints are high-value contributions! 🔒 |
