CVE-2026-31863 Â (opens in a new tab)How to fix?
Upgrade github.com/anyproto/anytype-heart/core/session to version 0.48.4 or higher.
Overview
Affected versions of this package are vulnerable to Brute Force in the challenge process. An attacker can gain unauthorized access to the local gRPC API by bypassing the 4-digit code authentication mechanism. This is only exploitable if the attacker has local user-level access to the machine, can discover the randomized listening port, and a vulnerable instance is running. In headless deployments, risk increases if a custom reverse proxy is configured to expose gRPC or gRPC-Web ports to external networks.
Workaround
This vulnerability can be mitigated by ensuring that any custom reverse proxy does not expose gRPC or gRPC-Web ports to external networks.
