Description

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

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.
Risk Scores
Base Score
3.6

The vulnerability requires local access to the device to be exploited. It is difficult for an attacker to exploit this vulnerability and may require special conditions. An attacker needs basic access or low-level privileges. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a low impact on the confidentiality of the information. There is a low impact on the integrity of the data.

Threat Intelligence
3.3

Limited exploitation activity has been observed. Close monitoring and planned remediation are recommended.
