GHSA-vv3h-7qwr-722v

#### Impact The challenge-based authentication for the local gRPC client API can be bypassed, allowing an attacker to gain access without the 4-digit code. Affected components: - Anytype Desktop (all platforms) ≤ v0.48.2 - Anytype-CLI (headless deployments) ≤ v0.1.9 Not affected: - Anytype mobile apps (iOS, Android) - do not expose a local gRPC server Who is impacted: This vulnerability is scoped to localhost. The gRPC and gRPC-Web ports bind to 127.0.0.1 only and are not exposed to the local network or internet. ### Exploitation requires: - Local user-level access to the machine running Anytype - Discovery of the randomized listening port - A running Anytype instance Anytype-CLI headless deployments may be at higher risk only if an administrator has chosen to set up their own reverse proxy and configured it in a way that exposes gRPC or gRPC-Web ports to an external network. **By default, these ports are not externally accessible and there is no built-in mechanism to expose them.** #### Patches - anytype-heart library: v0.48.4 - [Anytype Desktop](https://github.com/anyproto/anytype-ts): v0.54.5 - [Anytype-CLI](https://github.com/anyproto/anytype-cli): v0.1.11 #### Workarounds - Desktop users: No immediate action required. The vulnerability requires existing local access to the machine. - Anytype-CLI administrators: If using a custom reverse proxy, ensure it does not expose gRPC or gRPC-Web ports to external networks.
