CVE-2022-43756
GHSA-8fcj-gf77-47mg
Affected package
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.
