From cc6a5edfdf20ec7b574d98b926018e62924c5015 Mon Sep 17 00:00:00 2001 From: Jason Woltje Date: Mon, 2 Feb 2026 11:41:38 -0600 Subject: [PATCH] fix(#183): remove hardcoded workspace ID from Discord service Remove critical security vulnerability where Discord service used hardcoded "default-workspace" ID, bypassing Row-Level Security policies and creating potential for cross-tenant data leakage. Changes: - Add DISCORD_WORKSPACE_ID environment variable requirement - Add validation in connect() to require workspace configuration - Replace hardcoded workspace ID with configured value - Add 3 new tests for workspace configuration - Update .env.example with security documentation Security Impact: - Multi-tenant isolation now properly enforced - Each Discord bot instance must be configured for specific workspace - Service fails fast if workspace ID not configured Breaking Change: - Existing deployments must set DISCORD_WORKSPACE_ID environment variable Tests: All 21 Discord service tests passing (100%) Co-Authored-By: Claude Sonnet 4.5 --- .env.example | 6 + .../bridge/discord/discord.service.spec.ts | 85 ++++++++- .../api/src/bridge/discord/discord.service.ts | 8 +- .../183-remove-hardcoded-workspace-id.md | 170 ++++++++++++++++++ 4 files changed, 263 insertions(+), 6 deletions(-) create mode 100644 docs/scratchpads/183-remove-hardcoded-workspace-id.md diff --git a/.env.example b/.env.example index c890efc..3d4036f 100644 --- a/.env.example +++ b/.env.example @@ -171,6 +171,12 @@ GITEA_WEBHOOK_SECRET=REPLACE_WITH_RANDOM_WEBHOOK_SECRET # DISCORD_BOT_TOKEN=your-discord-bot-token-here # DISCORD_GUILD_ID=your-discord-server-id # DISCORD_CONTROL_CHANNEL_ID=channel-id-for-commands +# DISCORD_WORKSPACE_ID=your-workspace-uuid +# +# SECURITY: DISCORD_WORKSPACE_ID must be a valid workspace UUID from your database. +# All Discord commands will execute within this workspace context for proper +# multi-tenant isolation.
