Machine-written summary

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

PraisonAI's praisonaiagents package, versions before 4.5.128, exposes an AGUI endpoint (POST /agui) that has no authentication and sends a wildcard Access-Control-Allow-Origin header. A malicious website visited by a user running the AGUI server locally can trigger agent execution, including tool calls, and read the responses, which may expose file contents or other sensitive data. Upgrade praisonaiagents to version 4.5.128 or later; the source does not describe a workaround beyond not running the AGUI server while visiting untrusted sites.
