Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The metagpt package, versions up to and including 0.8.1, is vulnerable to eval injection in the ActionNode.xml_fill function's XML handling. A remote attacker can manipulate input so that dynamically evaluated code is executed. The source gives few details on the required access or exact impact. No fix is listed, and the source says a public exploit exists.
