This vulnerability affected GitHub Enterprise Server version 3.8.0 and above and was fixed in version 3.8.12, 3.9.7, 3.10.4, and 3.11.1.
The product checks the state of a resource before using that resource, but the resource’s state can change between the check and the use in a way that invalidates the results of the check. This can cause the product to perform invalid actions when the resource is in an unexpected state.
