Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Intake, PyPI package, versions up to and including 2.0.9, expands shell() syntax in parameter default values when a catalog source is accessed, so a crafted catalog YAML can run embedded commands on the host. An attacker would need to get a victim to load and access a malicious catalog, after which commands run with the victim's local user privileges. No fixed version is listed, and the source gives few details on exact behaviour.
