Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The ZeptoClaw crate (crates.io, versions before 0.7.6) has a webhook channel that trusts the sender and chat_id fields in the request body and checks the allowlist against them. Authentication is optional and disabled by default, so an attacker who can reach the POST /webhook endpoint can impersonate an allowlisted sender and pick arbitrary chat IDs. Upgrade to version 0.7.6 or later. Until then, configure an auth_token for the webhook channel.
