Short explanation
TAKO AI Agent for Okta contains an authenticated Python execution vulnerability through a validator bypass. Affecting versions prior to 3.0.1-beta, this flaw allows users to execute arbitrary Python source code.
Authenticated attackers can bypass security validations to execute code with elevated privileges, compromising the container and exposing sensitive data.
What should be done?
- Upgrade to version 3.0.1-beta
- Follow the vendor advisory
Chain of evidence and sources
3.0.1-beta öncesi TAKO AI Agent for Okta sürümlerinde fctr_session çerezine sahip kimliği doğrulanmış kullanıcılar, script_code alanından rastgele Python kaynağı gönderebilir.
Kod doğrulama denetimi AST hedef kontrollerindeki eksiklikler ve getattr kullanımı nedeniyle atlatılmaktadır.
Kabul edilen kod, varsayılan kapsayıcıda root yetkileri ile çalıştırılarak kapsayıcının ele geçirilmesine yol açar.
Show the technical text from the sources
TAKO AI Agent for Okta is a local-first AI agent that helps Okta administrators query tenant data using natural language. Prior to 3.0.1-beta, any authenticated user with a valid `fctr_session` cookie can submit arbitrary Python source in the `script_code` field of `POST /api/react/execute-script`, without administrator privilege. In `src/api/routers/react_stream.py`, the source is stored with `skip_discovery=True`, bypassing AI-based content filtering, and is passed to `validate_generated_code` in `src/utils/security_config.py`. `BLOCKED_PATTERNS` recognizes direct `__import__` calls but misses the import name passed as a string, `getattr` is in `ALLOWED_BUILTINS`, and the AST checker handles `ast.Name` and `ast.Attribute` targets but fails to handle `ast.Call` targets. Dynamic `getattr` call chains through `__builtins__` therefore evade validation. The `_write_temp_script` helper writes the accepted code to disk, and `asyncio.create_subprocess_exec()` executes it as the application process user, which is root in the default container. Command output is returned as Server-Sent Events through `GET /api/react/stream-react-updates?process_id=<id>`. The resulting container compromise can disclose environment secrets including Okta API tokens and the JWT key, expose the SQLite database, and permit backend-service pivoting and persistence. This issue is fixed in version 3.0.1-beta.
