Any authenticated session/API/MCP token holder can read any contributor's profile; for confirmed Gittensor miners that exposes `alphaPerDay`, `taoPerDay`, `usdPerDay` (and the `hotkey` on the REST path). Authenticated cross-contributor disclosure, CWE-284 / IDOR.\n \n### Details\n \nIn `src/api/routes.ts` the profile handler returns `buildContributorProfile(...)` with no `requireContributorAccess` call. Every sibling (`/decision-pack`, `/repos/:owner/:repo/decision`, etc.) gates and 403s on a cross-contributor request — the profile route is the only omission. `buildContributorProfile` (`src/signals/engine.ts`) embeds `hotkey` and the three `*PerDay` fields for any confirmed miner.\n \nThe MCP tool `getContributorProfile` (`src/mcp/server.ts`) also omits `requireContributorAccess`. Its `redactSensitiveForMcp` filter only strips keys matching `hotkey|coldkey|wallet|private_key|privateKey|mnemonic`, so the hotkey is dropped but `alphaPerDay`/`taoPerDay`/`usdPerDay` pass through.\n \nThe codebase treats these as secret everywhere else — `decision-pack.ts` destructures the hotkey out before serving, and three sanitizers scrub hotkey/wallet from AI/comment output — which is why this is an oversight, not by-design.\n \nExposure: REST → hotkey + 3 financial fields; MCP → 3 financial fields (hotkey redacted).\n \n### PoC\n \n1.
