fix(deps): bump google.golang.org/grpc to v1.79.3 (CVE-2026-33186) - #20
Merged
Conversation
gRPC-Go v1.79.1 and earlier have an authorization bypass where malformed :path headers (missing the leading slash) could bypass path-based restricted "deny" rules in interceptors like grpc/authz. v1.79.3 rejects any request with a non-canonical path with an Unimplemented error. Severity: Critical Ref: grpc/grpc-go#8981
