Impact A denial of services (DoS) vulnerability was discovered in Wrangler Git package affecting versions up to and including `v1.0.0`. 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. Workarounds 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. Patches Patched versions include `v1.0.1` and later and the backported tags - `v0.7.4-security1`, `v0.8.5-security1` and `v0.8.11`.
