Advisory details

Summary

Feishu allowlist authorization could be bypassed by display-name collision.

Details

channels.feishu.allowFrom is documented as an ID-based allowlist (open_id list), but Feishu policy matching accepted mutable sender display names in the same namespace. An attacker could set a display name equal to an allowlisted ID string and pass authorization checks.

The fix enforces ID-only matching for Feishu allowlist checks, normalizes Feishu ID prefixes during comparison, and ignores mutable display names for authorization.

Impact

Deployments using Feishu allowlist-based authorization could incorrectly authorize non-allowlisted senders when a colliding display name was used.
