Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
ZeptoClaw versions before 0.7.6 authorize email channel senders based only on the parsed From header, without checking SPF, DKIM, or DMARC results. An attacker who can get a forged message delivered to the monitored mailbox, for example where upstream sender authentication is weak or misconfigured, can impersonate an allowlisted sender and have the content processed as trusted input. Upgrade to ZeptoClaw 0.7.6 or later, and where possible enforce strict SPF, DKIM, and DMARC on inbound mail.
