security: pin all Python dependencies to exact versions#444
Merged
Conversation
Replace >= constraints with == pins across 4 files to prevent supply chain attacks (a malicious package version auto-installing on next deploy/build). - frontend_multi_user/pyproject.toml: 12 deps pinned - worker_plan/pyproject.toml: json_repair pinned - worker_plan_database/requirements.txt: 4 deps pinned - open_dir_server/requirements.txt: python-multipart pinned Dependabot will still propose version bumps via PRs, so updates remain easy to review and approve individually.

The recent litellm supply chain attack (compromised version live for ~3 hours) highlighted the risk of
>=constraints. With>=, anypip installor Docker build silently pulls the latest version — including a malicious one. Exact pins ensure only reviewed versions are installed.Test plan
