Summary: Denial of service when processing Git credentials in github.com/rancher/wrangler

Details: A denial of service (DoS) vulnerability exists in the Wrangler Git package. Specially crafted Git credentials can result in a denial of service (DoS) attack on an application that uses Wrangler due to the exhaustion of the available memory and CPU resources. This is caused by a lack of input validation of Git credentials before they are used, which may lead to a denial of service in some cases. This issue can be triggered when accessing both private and public Git repositories. A workaround is to sanitize input passed to the Git package to remove potential unsafe and ambiguous characters. Otherwise, the best course of action is to update to a patched Wrangler version.
