Failures are caught and only logged, so a GitHub user can ask Kilo to start work, get no visible response, and have no way to open the created session from GitHub. +- **Recommended fix:** Branch on `thread.adapter.name`: keep ephemeral cards for Slack, but post a normal GitHub reply with the session link or a safe handoff message for GitHub.

Any Kilo user who is a member of the owning organization can click someone else's visible link and complete OAuth for their own GitHub account. This likely does not hijack the original commenter because the callback links the OAuth-authenticated GitHub user ID, but it is an unintended enrollment path and can make public prompts misleading. +- **Recommended fix:** Human-verify the intended policy. If the link should only be usable by the triggering GitHub user, include that GitHub user ID in the signed token/state and verify it against the OAuth-authenticated GitHub user. If any org member may self-link from any prompt, update copy and tests to make that explicit. diff --git a/LEAK.md b/LEAK.md new file mode 100644 index 0000000000..8342a787ec --- /dev/null +++ b/LEAK.md @@ -0,0 +1,64 @@ +# Cross-Platform State Leak Review + +## Overall Conclusion + +I did not find a confirmed direct Slack-to-GitHub identity leak in the normal happy path.

The bot identity key is also only `identity:github:${installationId}:${githubUserId}`. +- **What would happen:** If the same GitHub installation ID exists for multiple Kilo owners, a GitHub mention can resolve to an arbitrary integration row. GitHub issue context comes from the real installation, but repository lists, profile config, org ID, billing/ownership, and Cloud Agent context can come from the wrong Kilo owner. +- **Impact:** Cross-tenant state leak across Kilo owners for GitHub bot requests, including possible wrong-owner Cloud Agent sessions. +- **Recommended fix:** Prefer a global unique constraint for active GitHub installation IDs if one GitHub App installation belongs to exactly one Kilo owner. If duplicates are valid, carry `platformIntegrationId` through the GitHub adapter/linking flow and key bot identity by `platformIntegrationId`, not only installation ID. Replace installation-only lookups with exact integration lookups. +- **Human verification:** Confirm whether duplicate active GitHub `platform_installation_id` rows are possible in production. + +### Medium: Bot session callbacks reconstruct the posting adapter from `platform_thread_id` without validating it matches the stored integration platform + +- **Affected files/functions:** `apps/web/src/app/api/internal/bot-session-callback/[botRequestId]/route.ts` (`POST`, `postBotThreadMessage`, `continueBotAgentAfterCallback`), `apps/web/src/lib/bot/run.ts`, `apps/web/src/lib/bot/request-logging.ts` +- **Leak scenario:** `processLinkedMessage()` stores `platform: thread.adapter.name` and `platform_thread_id: thread.id`. The callback later loads `platformIntegration` from `platform_integration_id`, then reconstructs the destination with `bot.thread(requestRow.platform_thread_id)`. There is no assertion that `requestRow.platform`, `platformIntegration.platform`, and the reconstructed thread adapter all match. +- **What would happen:** A corrupted or malformed bot request row could post a Slack-originated Cloud Agent result to a GitHub thread, or a GitHub-originated result through Slack context, while billing/logging/owner context comes from another platform. +- **Impact:** Cross-platform callback leakage is possible if persisted bot request state becomes inconsistent. This is probably not externally reachable in the normal path, but the callback endpoint trusts persisted state too much. +- **Recommended fix:** Before posting, assert `requestRow.platform === platformIntegration.platform`, `bot.thread(...).adapter.name === requestRow.platform`, and `bot.thread(...).adapter.name === platformIntegration.platform`.

The fetched content is injected into the prompt. +- **Impact:** Repository-to-repository context leakage inside the same GitHub installation, or cross-owner leakage if combined with wrong integration lookup. +- **Recommended fix:** Validate parsed `owner/repo` against `platformIntegration.repositories` before GitHub API calls.

The OAuth state carries only `userId` and `installationId`, and the callback resolves the integration again by installation ID only. +- **What would happen:** With stale/mismatched tokens or duplicate installation rows, the user can be authorized against one integration row and linked against another row selected by installation ID. +- **Impact:** Account-link state can drift away from the integration row that produced the link prompt. +- **Recommended fix:** In `/github/link`, reject tokens where `integration.platform !== 'github'` or installation IDs do not match.

The legacy path may skip, while the chat adapter still emits `onNewMention` and `handleIncomingMessage` processes it. +- **Impact:** Suspension may not stop GitHub bot runs or Cloud Agent sessions. +- **Recommended fix:** Gate the bot adapter path on the same active-integration and suspension checks as the legacy handler.

A different Kilo org member sees the public link and links their own GitHub account to that installation within the TTL. +- **Impact:** This likely does not let a completely unauthenticated external user run the bot, but it weakens identity binding and combines dangerously with missing repo-permission checks. +- **Recommended fix:** Include the original GitHub sender ID, repository, and issue/PR coordinates in the signed token and OAuth state.
