Machine-written summary

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

The praisonai package, versions before 4.6.78, accepts AgentMail webhook events without verifying their Svix signatures. A remote attacker who can reach the configured webhook URL can send forged message.received JSON, which the bot dispatches to the configured agent as an arbitrary sender, potentially causing unauthorized model use and replies from the inbox. Upgrade to praisonai 4.6.78, which is the listed fixed version.
