================
RestrictedPython
================

RestrictedPython is a tool that helps to define a subset of the Python language which allows to provide a program input into a trusted environment.
RestrictedPython is not a sandbox system or a secured environment, but it helps to define a trusted environment and execute untrusted code inside of it.

.. warning::

   RestrictedPython only supports CPython. It does _not_ support PyPy and other Python implementations as it cannot provide its restrictions there.

For full documentation please see http://restrictedpython.readthedocs.io/.

Example
=======

To give a basic understanding what RestrictedPython does here two examples:

An unproblematic code example
-----------------------------

Python allows you to execute a large set of commands.
This would not harm any system.

.. code-block:: pycon

    >>> from RestrictedPython import compile_restricted
    >>> from RestrictedPython import safe_globals
    >>>
    >>> source_code = """
    ... def example():
    ...     return 'Hello World!'
    ... """
    >>>
    >>> loc = {}
    >>> byte_code = compile_restricted(source_code, '<inline>', 'exec')
    >>> exec(byte_code, safe_globals, loc)
    >>>
    >>> loc['example']()
    'Hello World!'

Problematic code example
------------------------

This example directly executed in Python could harm your system.

.. code-block:: pycon

    >>> from RestrictedPython import compile_restricted
    >>> from RestrictedPython import safe_globals
    >>>
    >>> source_code = """
    ... import os
    ...
    ... os.listdir('/')
    ... """
    >>> byte_code = compile_restricted(source_code, '<inline>', 'exec')
    >>> exec(byte_code, safe_globals, {})
    Traceback (most recent call last):
    ImportError: __import__ not found

Changes
=======

7.4 (2024-10-09)
----------------

- Allow to use the package with Python 3.13.

- Drop support for Python 3.7.

- Provide new function ``RestrictedPython.Guards.safer_getattr_raise``.
  It is similar to ``safer_getattr`` but handles its parameter
  ``default`` like ``getattr``, i.e. it raises ``AttributeError``
  if the attribute lookup fails and this parameter is not provided,
  fixes `#287 <https://github.com/zopefoundation/RestrictedPython/issues/287>`_.


7.3 (2024-09-30)
----------------

- Increase the safety level of ``safer_getattr`` allowing applications to use
  it as ``getattr`` implementation. Such use should now follow the same policy
  and give the same level of protection as direct attribute access in an
  environment based on ``RestrictedPython``'s ``safe_builtints``.
- Prevent information leakage via ``AttributeError.obj``
  and the ``string`` module. (CVE-2024-47532)


7.2 (2024-08-02)
----------------

- Remove unneeded setuptools fossils that may cause installation problems
  with recent setuptools versions.
- Add support for single mode statements / execution.
- Fix a potential breakout capability in the provided ``safer_getattr`` method
  that is part of the ``safer_builtins``.


7.1 (2024-03-14)
----------------

- Add support for the matmul (``@``) operator.


7.0 (2023-11-17)
----------------

Backwards incompatible changes
++++++++++++++++++++++++++++++

- Drop support for Python 3.6.

Features
++++++++

- Officially support Python 3.12.

Fixes
+++++

- Prevent DeprecationWarnings from ``ast.Str`` and ``ast.Num`` on Python 3.12

- Forbid using some attributes providing access to restricted Python internals.
  (CVE-2023-37271)

- Fix information disclosure problems through Python's "format" functionality
  (``format`` and ``format_map`` methods on ``str`` and its instances,
  ``string.Formatter``). (CVE-2023-41039)


6.0 (2022-11-03)
----------------

Backwards incompatible changes
++++++++++++++++++++++++++++++

- Drop support for Python 2.7 and 3.5.

Features
++++++++

- Officially support Python 3.11.

- Allow to use the Python 3.11 feature of exception groups and except\*
  (PEP 654).


5.2 (2021-11-19)
----------------

- Document that ``__name__`` is needed to define classes.

- Add support for Python 3.10. Auditing the Python 3.10 change log did not
  reveal any changes which require actions in RestrictedPython.

- Avoid deprecation warnings when using Python 3.8+.
  (`#192 <https://github.com/zopefoundation/RestrictedPython/issues/192>`_)


5.1 (2020-10-07)
----------------

Features
++++++++

- Add support for (Python 3.8+) assignment expressions (i.e. the ``:=`` operator)

- Add support for Python 3.9 after checking the security implications of the
  syntax changes made in that version.

- Add support for the ``bytes`` and ``sorted`` builtins
  (`#186 <https://github.com/zopefoundation/RestrictedPython/issues/186>`_)

Documentation
+++++++++++++

- Document parameter ``mode`` for the ``compile_restricted`` functions
  (`#157 <https://github.com/zopefoundation/RestrictedPython/issues/157>`_)

- Fix documentation for ``compile_restricted_function``
  (`#158 <https://github.com/zopefoundation/RestrictedPython/issues/158>`_)

Fixes
+++++

- Fix ``compile_restricted_function`` with SyntaxErrors that have no text
  (`#181 <https://github.com/zopefoundation/RestrictedPython/issues/181>`_)

- Drop install dependency on ``setuptools``.
  (`#189 <https://github.com/zopefoundation/RestrictedPython/issues/189>`_)


5.0 (2019-09-03)
----------------

Breaking changes
++++++++++++++++

- Revert the allowance of the ``...`` (Ellipsis) statement, as of 4.0. It is
  not needed to support Python 3.8.
  The security implications of the Ellipsis Statement is not 100 % clear and is
  not checked. ``...`` (Ellipsis) is disallowed again.

Features
++++++++

- Add support for f-strings in Python 3.6+.
  (`#123 <https://github.com/zopefoundation/RestrictedPython/issues/123>`_)


4.0 (2019-05-10)
----------------

Changes since 3.6.0:

Breaking changes
++++++++++++++++

- The ``compile_restricted*`` functions now return a
  ``namedtuple CompileResult`` instead of a simple ``tuple``.

- Drop the old implementation of version 3.x: `RCompile.py`,
  `SelectCompiler.py`, `MutatingWorker.py`, `RestrictionMutator.py` and
  `tests/verify.py`.

- Drop support for long-deprecated ``sets`` module.

Security related issues
+++++++++++++++++++++++

- RestrictedPython now ships with a default implementation for
  ``_getattr_`` which prevents from using the ``format()`` method on
  str/unicode as it is not safe, see:
  http://lucumr.pocoo.org/2016/12/29/careful-with-str-format/

  **Caution:** If you do not already have secured the access to this
  ``format()`` method in your ``_getattr_`` implementation use
  ``RestrictedPython.Guards.safer_getattr()`` in your implementation to
  benefit from this fix.

Features
++++++++

- Mostly complete rewrite based on Python AST module.
  [loechel (Alexander Loechel), icemac (Michael Howitz),
  stephan-hof (Stephan Hofmockel), tlotze (Thomas Lotze)]

- Add support for Python 3.5, 3.6, 3.7.

- Add preliminary support for Python 3.8. as of 3.8.0a3 is released.

- Warn when using another Python implementation than CPython as it is not safe
  to use RestrictedPython with other versions than CPyton.
  See https://bitbucket.org/pypy/pypy/issues/2653 for PyPy.

- Allow the ``...`` (Ellipsis) statement. It is needed to support Python 3.8.

- Allow `yield` and `yield from` statements.
  Generator functions would now work in RestrictedPython.

- Allow the following magic methods to be defined on classes.
  (`#104 <https://github.com/zopefoundation/RestrictedPython/issues/104>`_)
  They cannot be called directly but by the built-in way to use them (e. g.
  class instantiation, or comparison):

  + ``__init__``
  + ``__contains__``
  + ``__lt__``
  + ``__le__``
  + ``__eq__``
  + ``__ne__``
  + ``__gt__``
  + ``__ge__``

- Imports like ``from a import *`` (so called star imports) are now forbidden
  as they allow to import names starting with an underscore which could
  override protected build-ins.
  (`#102 <https://github.com/zopefoundation/RestrictedPython/issues/102>`_)

- Allow to use list comprehensions in the default implementation of
  ``RestrictionCapableEval.eval()``.

- Switch to pytest as test runner.

- Bring test coverage to 100 %.

Bug fixes
+++++++++

- Improve `.Guards.safer_getattr` to prevent accessing names starting with
  underscore.
  (`#142 <https://github.com/zopefoundation/RestrictedPython/issues/142>`_)


3.6.0 (2010-07-09)
------------------

- Add name check for names assigned during imports using the
  ``from x import y`` format.

- Add test for name check when assigning an alias using multiple-context
  ``with`` statements in Python 2.7.

- Add tests for protection of the iterators for dict and set comprehensions
  in Python 2.7.

3.6.0a1 (2010-06-05)
--------------------

- Remove support for ``DocumentTemplate.sequence`` - this is handled in the
  DocumentTemplate package itself.

3.5.2 (2010-04-30)
------------------

- Remove a testing dependency on ``zope.testing``.

3.5.1 (2009-03-17)

- Filter DeprecationWarnings when importing Python's ``sets`` module.

3.5.0 (2009-02-09)
------------------

- Drop legacy support for Python 2.1 / 2.2 (``__future__`` imports
  of ``nested_scopes`` / ``generators``.).

3.4.3 (2008-10-26)
------------------

- Fix deprecation warning: ``with`` is now a reserved keyword on
  Python 2.6. That means RestrictedPython should run on Python 2.6
  now. Thanks to Ranjith Kannikara, GSoC Student for the patch.

- Add tests for ternary if expression and for ``with`` keyword and
  context managers.

3.4.2 (2007-07-28)

Thanks to Ranjith Kannikara, GSoC Student for the patch.\n\n- Add tests for ternary if expression and for ``with`` keyword and\n  context managers.\n\n3.4.2 (2007-07-28)\n------------------\n\n- Changed homepage URL to the PyPI site\n\n- Improve ``README.txt``.\n\n3.4.1 (2007-06-23)\n------------------\n\n- Fix http://www.zope.org/Collectors/Zope/2295: Bare conditional in\n  a Zope 2 PythonScript followed by a comment causes SyntaxError.\n\n3.4.0 (2007-06-04)\n------------------\n\n- RestrictedPython now has its own release cycle as a separate project.\n\n- Synchronized with RestrictedPython from Zope 2 tree.\n\n3.2.0 (2006-01-05)\n------------------\n\n- Corresponds to the verison of the RestrictedPython package shipped\n  as part of the Zope 3.2.0 release.\n\n- No changes from 3.1.0.\n\n3.1.0 (2005-10-03)\n------------------\n\n- Corresponds to the verison of the RestrictedPython package shipped\n  as part of the Zope 3.1.0 release.\n\n- Remove unused fossil module, ``SafeMapping``.\n\n- Replaced use of deprecated ``whrandom`` module with ``random`` (aliased\n  to ``whrandom`` for backward compatibility).\n\n3.0.0 (2004-11-07)\n------------------\n\n- Corresponds to the verison of the RestrictedPython package shipped\n  as part of the Zope X3.0.0 release.\n",
