How to Fix GHSA-m425-mq94-257g

To remediate this vulnerability, upgrade all affected Google.golang.org/grpc dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

google.golang.org/grpc fixed: 1.56.3 
Upgrade google.golang.org/grpc to 1.56.3
google.golang.org/grpc fixed: 1.57.1 
Upgrade google.golang.org/grpc to 1.57.1
google.golang.org/grpc fixed: 1.58.3 
Upgrade google.golang.org/grpc to 1.58.3
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for google.golang.org/grpc

How to Check if You Are Affected

To determine whether your application is affected by GHSA-m425-mq94-257g, inspect your project dependencies for Google.golang.org/grpc:

inspect dependencies for google.golang.org/grpc

Analyze the terminal output to locate any version of Google.golang.org/grpc in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.56.3), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In Google.golang.org/grpc, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact In affected releases of gRPC-Go, it is possible for an attacker to send HTTP/2 requests, cancel them, and send subsequent requests, which is valid by the HTTP/2 protocol, but would cause the gRPC-Go server to launch more concurrent method handlers than the configured maximum stream limit. ### Patches This vulnerability was addressed by #6703 and has been included in patch releases: 1.56.3, 1.57.1, 1.58.3. It is also included in the latest release, 1.59.0. Along with applying the patch, users should also ensure they are using the `grpc.MaxConcurrentStreams` server option to apply a limit to the server's resources used for any single connection. ### Workarounds None. ### References #6703
