Description

Raises the protobuf upper bound from <6.32 to <7.0 so users on the 6.x line can upgrade to 6.33.5+ which contains the fix for CVE-2026-0994.

The minimum remains >=3.12 to avoid breaking existing environments on protobuf 4.x/5.x.

Motivation

Protobuf 6.31.1 (currently allowed by the <6.32 ceiling) has an open CVE (CVE-2026-0994). The fix is available in protobuf 6.33.5, but the current upper bound prevents users from upgrading.

Fixes #5548

Changes

  • pyproject.toml: Changed protobuf>=3.12,<6.32 to protobuf>=3.12,<7.0

Testing

This is a dependency constraint change only — no code changes. Existing tests should pass as-is since protobuf maintains backward compatibility within major versions.
