How to fix?
Upgrade github.com/mostynb/go-grpc-compression/internal/zstd to version 1.2.3 or higher.
Overview
Affected versions of this package are vulnerable to Uncontrolled Resource Consumption ('Resource Exhaustion') through the Decoder.DecodeAll function. An attacker can cause rapid memory usage increases by sending specially crafted gRPC requests.
Note: This is only exploitable if attackers can send gRPC payloads to users of the affected libraries.
Workaround
Other compression formats were not affected, users may consider switching from zstd to another format without upgrading to a newer release.
