Description
What does this PR do ?
This PR addresses a critical authorization bypass vulnerability in gRPC‑Go (CVE‑2026‑33186).
Older versions of gRPC‑Go allowed malformed HTTP/2 :path values without a leading slash, which could bypass path‑based authorization rules under certain policy configurations.
Fix :
1.Upgraded google.golang.org/grpc from v1.56.3 to v1.79.3
2.This version rejects malformed :path headers before routing or authorization logic runs, fully mitigating the vulnerability upstream
3.No application‑level logic changes were required
Key Changes :
1.Dependency upgrade: google.golang.org/grpc v1.79.3
2.Related transitive dependency updates via go mod tidy
3.No functional or behavioral changes to plugin logic
