Zope: >> Restrictedpython >> 5.3 Security Vulnerabilities
RestrictedPython is a restricted execution environment for Python to run untrusted code. A user can gain access to protected (and potentially sensible) information indirectly via AttributeError.obj and the string module. The problem will be fixed in version 7.3. As a workaround, If the application does not require access to the module string, it can remove it from RestrictedPython.Utilities.utility_builtins or otherwise do not make it available in the restricted execution environment.

RestrictedPython is a restricted execution environment for Python to run untrusted code. Python's "format" functionality allows someone controlling the format string to "read" all objects accessible through recursive attribute lookup and subscription from objects he can access. This can lead to critical information disclosure. With `RestrictedPython`, the format functionality is available via the `format` and `format_map` methods of `str` (and `unicode`) (accessed either via the class or its instances) and via `string.Formatter`. All known versions of `RestrictedPython` are vulnerable. This issue has been addressed in commit `4134aedcff1` which has been included in the 5.4 and 6.2 releases. Users are advised to upgrade. There are no known workarounds for this vulnerability.
