…ralio#9611) ## Summary Bumps dependencies to address security CVEs on `main`: - **CVE-2026-33186 (CRITICAL)**: `google.golang.org/grpc` v1.72.2 → v1.79.3 — authorization bypass via missing leading `/` in `:path` header - **CVE-2026-22184 (HIGH)**: Alpine `zlib` 1.3.1-r2 → 1.3.2-r0 — global buffer overflow in `untgz` utility Note: The other two CVEs from the v1.30.2 security review are already addressed on `main`: - otel/sdk v1.40.0 — already landed via temporalio#9442 - Go stdlib — `main` is on Go 1.26.0 (separate release series) ## Risk assessment - **grpc v1.72.2 → v1.79.3**: 7 minor version jump with ~23 transitive dependency upgrades. Builds cleanly. Same bump successfully applied to `release/v1.30.x` in temporalio#9610. - **zlib**: Alpine package upgrade via `apk upgrade --no-cache zlib` in both server and admin-tools Dockerfiles. ## Test plan - [ ] CI passes Made with [Cursor](https://cursor.com)
