| description: | |
| 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. |
