Bumps google.golang.org/grpc from 1.78.0 to 1.79.3.

Release notes

Sourced from google.golang.org/grpc's releases.

Release 1.79.3

Security

  • server: fix an authorization bypass where malformed :path headers (missing the leading slash) could bypass path-based restricted "deny" rules in interceptors like grpc/authz. Any request with a non-canonical path is now immediately rejected with an Unimplemented error. (#8981)

Release 1.79.2

Bug Fixes

  • stats: Prevent redundant error logging in health/ORCA producers by skipping stats/tracing processing when no stats handler is configured. (grpc/grpc-go#8874)

Release 1.79.1

Bug Fixes

Release 1.79.0

API Changes

  • mem: Add experimental API SetDefaultBufferPool to change the default buffer pool. (#8806)
  • experimental/stats: Update MetricsRecorder to require embedding the new UnimplementedMetricsRecorder (a no-op struct) in all implementations for forward compatibility. (#8780)

Behavior Changes

  • balancer/weightedtarget: Remove handling of Addresses and only handle Endpoints in resolver updates. (#8841)

New Features

  • experimental/stats: Add support for asynchronous gauge metrics through the new AsyncMetricReporter and RegisterAsyncReporter APIs. (#8780)
  • pickfirst: Add support for weighted random shuffling of endpoints, as described in gRFC A113.
    • This is enabled by default, and can be turned off using the environment variable GRPC_EXPERIMENTAL_PF_WEIGHTED_SHUFFLING. (#8864)
  • xds: Implement :authority rewriting, as specified in gRFC A81. (#8779)
  • balancer/randomsubsetting: Implement the random_subsetting LB policy, as specified in gRFC A68. (#8650)

Bug Fixes

  • credentials/tls: Fix a bug where the port was not stripped from the authority override before validation. (#8726)
  • xds/priority: Fix a bug causing delayed failover to lower-priority clusters when a higher-priority cluster is stuck in CONNECTING state. (#8813)
  • health: Fix a bug where health checks failed for clients using legacy compression options (WithDecompressor or RPCDecompressor). (#8765)
  • transport: Fix an issue where the HTTP/2 server could skip header size checks when terminating a stream early. (#8769)
  • server: Propagate status detail headers, if available, when terminating a stream during request header processing. (#8754)

Performance Improvements

  • credentials/alts: Optimize read buffer alignment to reduce copies. (#8791)
  • mem: Optimize pooling and creation of buffer objects. (#8784)
  • transport: Reduce slice re-allocations by reserving slice capacity. (#8797)

Pull Request Overview

This PR updates google.golang.org/grpc from 1.78.0 to 1.79.3. Although the Codacy analysis is 'up to standards', this version includes a security fix (CVE-2025-24968) that introduces a breaking behavior change: requests with non-canonical paths (e.g., missing a leading slash) will now be rejected with an 'Unimplemented' error. This change, along with the transition from 'Address' handling to 'Endpoints' in load balancing, represents a significant regression risk for existing client implementations and custom balancing configurations.

About this PR

  • The gRPC security fix introduces a breaking change where non-canonical paths are rejected. Verify that all client implementations (including those not using standard gRPC libraries) send valid, canonical paths to avoid service disruption.

Test suggestions

  • Verify application compilation and initialization with gRPC 1.79.3.
  • Verify that gRPC server interceptors/rules still function correctly given the new strict path checking (security fix #8981).
  • Confirm that existing load balancing configurations (specifically weighted targets) are compatible with the removal of Address handling in favor of Endpoints.
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify application compilation and initialization with gRPC 1.79.3.
2. Verify that gRPC server interceptors/rules still function correctly given the new strict path checking (security fix #8981).
3. Confirm that existing load balancing configurations (specifically weighted targets) are compatible with the removal of Address handling in favor of Endpoints.
Low confidence findings
  • The update includes experimental API changes (e.g., mem.SetDefaultBufferPool) and shifts from Address to Endpoints in load balancing. Review any internal extensions or custom balancers to ensure compatibility with these removals.
