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.
The issue will be fixed in 5.4 and 6.2.
There are no workarounds to fix the issue without upgrading.
