Name of the Vulnerable Software and Affected Versions Bundler versions 1.x

Description The issue is related to a gem name collision on a secondary source, which could allow remote attackers to inject arbitrary Ruby code into an application. This might lead to unauthorized access to confidential data, disruption of data integrity, and denial of service.

Recommendations For Bundler version 1.x, consider implementing measures to handle gem name collisions securely, such as ensuring unique gem names or validating gem sources to prevent arbitrary code injection. As a temporary workaround, consider restricting access to secondary gem sources until a more robust solution is available.
