Name of the Vulnerable Software and Affected Versions Swagger-Parser versions <= 1.0.30 Swagger codegen versions <= 2.2.2

Description A vulnerability in Swagger-Parser's yaml parsing functionality results in arbitrary code being executed when a maliciously crafted yaml Open-API specification is parsed. This affects the 'generate' and 'validate' commands in swagger-codegen and can lead to arbitrary code being executed when these commands are used on a well-crafted yaml specification.

Recommendations For Swagger-Parser versions <= 1.0.30, update to a version greater than 1.0.30 to resolve the issue. For Swagger codegen versions <= 2.2.2, update to a version greater than 2.2.2 to resolve the issue. As a temporary workaround, consider restricting the use of the 'generate' and 'validate' commands in swagger-codegen until a patch is available.
