Changes

Changes since 1.23.2: https://github.com/HumanSignal/label-studio/compare/1.23.2...nightly

This is a security-focused patch release. Please read the upgrade notes before you upgrade.

⚠️ Upgrade notes

• PostgreSQL 14 or higher is now required. Label Studio now runs on Django 5.2, which doesn't support PostgreSQL 13 or older.

• New secure defaults:

  • SSRF_PROTECTION_ENABLED=true: outbound requests to private or local network addresses are blocked. This affects URL imports, webhooks, S3-compatible endpoints, and Redis storage.
  • ML_BLOCK_LOCAL_IP=true: ML backends on localhost or a private network are blocked.
  • DEBUG_MODAL_EXCEPTIONS=false: error details are no longer shown in the UI.

  If your ML backend, MinIO, Redis, or webhook receiver runs on a local or private network, set SSRF_PROTECTION_ENABLED=false and/or ML_BLOCK_LOCAL_IP=false. Alternatively, keep the protection on and change the blocked ranges with USE_DEFAULT_BANNED_SUBNETS and USER_ADDITIONAL_BANNED_SUBNETS.

Security

• Stronger SSRF protection for ML backends, webhooks, cloud storage, and URL imports.
• Tighter permission checks when you create storages, webhooks, and ML backends, and when you delete users.
• Fixed access checks for local file storage and Data Manager filters.
• Improved HTML sanitization in the labeling interface.

Helm Chart version: 2.0.0

✅ Feature updates

⬆️⬇️ Sort video, audio, and timeseries regions by start time

You can now sort regions by media start time. (#8418)

📁 Improved Local Storage setup process

This release improves numerous Local Storage setup improvements to help make the process easier for users. (#8891)

Changes include:

• When entering the absolute local path in the storage modal, trailing slashes will be automatically removed to prevent an error.
• Normalized slashes when saving the absolute local path to prevent confusion between Unix and Windows environments.
• If you create folders named "my-data" or "label-studio-data" and run the label-studio command in the parent directory, the LOCAL_FILES_DOCUMENT_ROOT and LOCAL_FILES_SERVING_ENABLED variables will be automatically set to point to those folders.
• Improved error messages when the absolute local path does not include a subdirectory but matched the local files document root.
• When the local files document root is set, the absolute local path is automatically preloaded with the appropriate path.

❗️ Additional validation when performing destructive actions in projects
