Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The datamodel-code-generator package, versions 0.25.0 up to but not including 0.60.1, can generate Python code with injected content when a GraphQL Union type has a description containing a carriage return escape. An attacker who supplies or influences the GraphQL schema processed by the tool can get arbitrary Python code written into the generated module, which runs when that module is imported, with the importing process's privileges. Upgrade to datamodel-code-generator 0.60.1 or later, which normalizes carriage returns in these descriptions.
